Nuclear Medicine — Specialty Profile

Exploratory, not prescriptive. This profile blends hard data (pay, entry routes, demographics — each sourced and dated) with generalizations and synthesized online opinion about culture and "who fits." It's here to help you get curious and go find out for yourself — not to tell you who to become. Numbers marked ⟳ verify change every year; check the linked source before you quote one. Last reviewed: 2026-07-26.

Also called: nuc med, NM, molecular imaging & therapy. A small base specialty with several front doors: you can enter through a dedicated Nuclear Medicine residency, or reach it from Diagnostic Radiology, or from another clinical specialty. Organ systems: all of them, because nuclear medicine is the specialty of physiology and molecular function, imaged and treated with radioactive tracers, across every organ.

The 30-second version

Nuclear medicine is the specialty that sees, and increasingly treats, the body by its function rather than only its shape. Where a CT or MRI shows structure (is there a mass, where is it), nuclear medicine shows behavior: which cells are metabolizing sugar fast enough to be cancer, whether heart muscle is getting blood, how a thyroid is working, whether bone is laying down repair. You do this by giving the patient a tiny amount of a radioactive tracer that homes to a specific target, then imaging where it went with a PET or SPECT camera. The part that's changing the field: once you can see a target, you can attach a therapeutic isotope to the same molecule and treat it, delivering radiation from the inside, straight to the tumor. "See and treat function" is the whole idea, and it has a name that has turned a quiet field into a growth story: theranostics.

What they actually do

Nuclear medicine physicians use radiopharmaceuticals, molecules tagged with a radioactive atom, to image how the body is functioning and, increasingly, to treat disease. The core divide in the field is between diagnostics (the imaging) and therapy (the treatment), and most nuclear physicians do both.

On the imaging side, the daily bread is functional and molecular studies: PET-CT (usually FDG, a radioactive glucose analog, to stage and follow cancers, and increasingly PSMA-PET for prostate and DOTATATE-PET for neuroendocrine tumors); SPECT studies; myocardial perfusion imaging (is the heart getting blood under stress); bone scans (metastases, occult fractures, infection); thyroid uptake and scans; hepatobiliary (HIDA) scans; renal scans; and V/Q lung scans for pulmonary embolism when CT isn't an option. The interpretive skill is different from plain radiology: you're reading physiology on a map of anatomy: where the signal is bright, what "bright" means for this tracer, and what's physiologic versus pathologic uptake.1

On the therapy side, the part driving the field's momentum, nuclear physicians prescribe and deliver radiation from the inside. The classic example is radioactive iodine (I-131) for hyperthyroidism and thyroid cancer, used for decades. The new wave is theranostics: pair a targeting molecule with a diagnostic isotope to find disease, then the same molecule with a therapeutic isotope to treat it. In practice today that means Lu-177 PSMA (Pluvicto) for metastatic prostate cancer, Lu-177 DOTATATE (Lutathera) for neuroendocrine tumors, Y-90 radioembolization for liver tumors, and Ra-223 for bone-metastatic prostate cancer. This is real, hands-on oncology-adjacent care: you consult on eligibility, calculate and administer doses, manage radiation safety, and follow patients through cycles of treatment.23

Representative work & procedures: interpreting PET-CT, SPECT, bone, cardiac perfusion, thyroid, HIDA, renal, and V/Q studies · protocoling and supervising tracer administration · I-131 therapy for thyroid disease and cancer · Lu-177 PSMA and Lu-177 DOTATATE infusions · Y-90 radioembolization (with interventional radiology) · Ra-223 administration · dosimetry (calculating how much radiation a target actually receives) · radiation-safety oversight and regulatory compliance · consulting with oncology, cardiology, endocrinology, and surgery.

A day in the life: Much of the day looks like a reading room: you pull functional studies off a worklist and dictate reports, often alongside the CT component of a PET-CT. But woven through it is the therapy clinic: you see a patient being worked up for Lu-177 PSMA, confirm they meet criteria, review their PSMA-PET, and later supervise the infusion; you counsel a thyroid-cancer patient before I-131 and handle the radiation-safety instructions for going home; you sign off on dose calculations. There's real patient contact here that the "radiology doesn't see patients" stereotype misses. Acute overnight call is light in most settings, because the work is scheduled, daytime, and clinic-and-console based rather than driven by crashing patients.12

The training path & time to completion

This is the part premeds find genuinely confusing about nuclear medicine, and it's worth getting right: there is no single front door. Nuclear medicine can be entered through several routes, and it is certified by two different boards: the American Board of Nuclear Medicine (ABNM) and, for the radiology routes, the ABR (Nuclear Radiology).4

The main routes:45

  • (a) Dedicated Nuclear Medicine residency. After medical school and one clinical year (an internship with ≥9 months of direct patient care), you do 36 months in an ACGME-accredited Nuclear Medicine program → board-eligible with ABNM. The clinical year comes before the 36 months rather than inside them, so this is 4 years post-MD. It is still the fastest route.
  • (b) Diagnostic Radiology → Nuclear Radiology fellowship. Finish a full DR residency (intern year + 4 years), then a 1-year Nuclear Radiology fellowship → ABR Nuclear Radiology certification. This is the route most current nuclear imaging is read through, because it comes bundled with full radiology training.
  • (c) Integrated / combined DR-NM pathways. Programs offer 16 months of nuclear medicine training embedded within a DR residency (the ABR "16-month pathway"), or combined tracks that lead to nuclear certification without a separate fellowship year. There are also longer combined programs (e.g., Internal Medicine / Nuclear Medicine, ~4 years).45
  • (d) From another specialty. Physicians already trained in another ABMS specialty (e.g., internal medicine, oncology-adjacent fields) can enter via ~2 years in an ACGME nuclear medicine program, with up to a year of prior training credited.4

A hard requirement common to all routes: the NRC-mandated radiation-safety training (on the order of ~700 hours of authorized-user training in handling unsealed radioactive materials), which is what legally lets you administer therapeutic isotopes.4

Total from the start of college: ~12 years via the dedicated NM residency route (4 undergrad + 4 med school + 1 clinical year + 3 NM residency); the radiology routes run longer (13+ years) because you're completing a full DR residency first.

Related: because so much nuclear imaging is read by radiologists, the place to start is Diagnostic Radiology alongside this, because the two fields overlap heavily and many people arrive at theranostics through radiology.

How competitive is it?

Nuclear medicine is a small field, and by the usual metrics it is among the least competitive base specialties, which is a double-edged fact rather than a knock.

  • The dedicated Nuclear Medicine residency pool is tiny, a handful of positions across a small number of programs, and it has historically gone unfilled, with spots regularly available outside the main match and through post-match processes.5 ⟳
  • The small pool makes it comparatively DO- and IMG-accessible relative to the competitive imaging and procedural fields, an unusual open door in a landscape where most imaging is tightening.5 ⟳
  • Because the radiology route (b/c above) is the dominant path into nuclear imaging, many strong applicants who want to do this work enter through Diagnostic Radiology first, which is itself competitive and rising (see the DR profile). So "how competitive is nuclear medicine" splits in two: the direct NM residency is low-competition; the radiology-then-nuclear path inherits radiology's competitiveness.5

The honest read: if your goal is functional imaging and theranostics and you're flexible about the route, nuclear medicine is one of the more reachable fields in medicine right now, genuinely open to applicants who don't have a competitive-specialty pedigree. The same smallness that makes it reachable is also the honest risk, and it shows up in the job market and workforce sections below. Limited match data is published for such a small field; treat any single year's numbers as noisy and verify against NRMP directly.5

Compensation

Nuclear medicine pay is mid-range for physicians: comfortably into six figures, below the procedural and high-volume imaging fields, and not as well-documented as bigger specialties (many national surveys fold it into radiology or report it on small samples). Read the numbers as a band, not a precise point.

National number. Aggregated salary databases for 2025–26 put the nuclear medicine physician median around $388,000, with a range roughly $344,000 (10th pct) to $466,000 (90th pct) (Salary.com, 2026); the other anchor is lower and much thinner: Marit Health's self-reported panel of eleven nuclear medicine physicians, updated June 2026, averages $375,421.67 A defensible "typical full-time" figure for 2025–26 is ~$375,000–$400,000 total compensation, and it is worth knowing exactly what holds it up: an HR-reported employer benchmark that runs base-weighted, and a crowd panel of eleven people. No national physician compensation survey publishes a nuclear medicine line, and BLS has no wage series for the occupation at all. Treat the band as the best available rather than as a measurement, and benchmark any offer against the specific practice's therapy volume. ⟳

What moves it. As in most fields, practice setting (academic vs. hospital-employed vs. private), geography, and volume/therapy mix matter more than seniority. Academic and pure-imaging roles tend to sit lower; roles anchored to a busy theranostics or therapy program, where the field's reimbursement growth is concentrated, are where the upside is emerging. Clean, audited percentile and subspecialty breakouts specific to nuclear medicine are limited; where you see them, they're usually recruiter or crowdsourced estimates rather than MGMA-grade data.67 ⟳

The trend that colors all of it: theranostics. This is the real compensation story, and it's about trajectory more than today's paycheck. The radiopharmaceutical market was valued around $750 million in 2022 and is projected to reach ~$5.5 billion by 2028, with 80+ radiopharmaceutical candidates in clinical development and back-to-back blockbuster approvals (Lu-177 DOTATATE, then Lu-177 PSMA with an expanding label).23 Professional societies are openly warning of a workforce bottleneck, and that the coming volume of radiopharmaceutical therapy could require hundreds of new treatment centers and far more trained physicians than the pipeline currently produces.2 That mismatch of surging demand against a small trained workforce is a genuine tailwind for the value of a nuclear-trained physician over a career, even if this year's median still reads "mid-range." Frame it honestly: the growth is real and well-documented; whether and how fast it converts into individual pay is not yet visible in the salary surveys. ⟳

Lifestyle

Nuclear medicine is widely regarded as one of the more controllable lifestyles in medicine, and the reasons are structural:

  • Largely daytime work. The mix of reading-room interpretation and scheduled therapy clinic means the day has a shape: studies and appointments are booked rather than walking in crashing.
  • Low acute call. Overnight and weekend call burden is light in most settings compared with EM, surgery, or even general radiology's nighthawk demands. Tracers and therapies are scheduled; true emergencies are uncommon.
  • Clinic + console, not OR or floor. The physical day is seated and cognitive, covering imaging interpretation, dose planning, and patient counseling, with real but manageable patient contact on the therapy side.
  • Good career longevity. Like diagnostic radiology, it's a field you can sustain into later career, with no physically punishing procedures and no lifelong overnight grind. That durability is a genuine selling point.

The trade, as with any imaging-heavy field, is worklist/throughput pressure on the diagnostic side and the administrative weight of radiation-safety and regulatory compliance on the therapy side. Both are real without carrying the acute-stress profile of the front-line specialties.

Lifestyle rating: 4/5. Strong schedule control, daytime hours, and light acute call, docked because imaging throughput and the regulatory overhead of running therapies are constant background load. (Directional; NM-specific lifestyle survey data is limited.) ⟳

Wellbeing — the part to take seriously

Here the honest answer is limited specialty-specific data: nuclear medicine is too small to appear as its own line in most burnout and happiness surveys, and it's often absorbed into "radiology." So the most defensible thing to say is a neighborhood, not a number.

  • Burnout: No stable NM-specific figure. Its closest well-measured neighbor, diagnostic radiology, sits slightly above the all-physician average: the AMA's 2025 Organizational Biopsy puts radiology at 45.2% against a 41.9% baseline, fifth of the nine specialties it names as most burned out. Medscape reads it the same direction on its own scale, ~51% against a 49% average in 2024 and ~36% in the 2022 edition, which used a different instrument.8 Nuclear medicine's lighter call and lower acuity plausibly put it at or below that, but treat this as inference rather than measurement. ⟳
  • Career longevity: This is a genuine strength. The absence of overnight-heavy call and physically demanding procedures makes it one of the more sustainable-to-late-career fields, and the theranostics growth gives senior physicians an expanding, meaningful role rather than a treadmill to escape.
  • The quiet stressor unique to nuclear medicine is regulatory and safety weight. You are the authorized user legally responsible for radioactive material, and that carries a low-grade, constant conscientiousness burden that doesn't show up in generic burnout surveys.

Write "limited data" here rather than inventing a burnout percentage for a field this small, and if you need a number, pull the current-year Medscape radiology figure as the nearest proxy and label it as such.

Who's in the field (demographics)

Nuclear medicine's small size means most demographic breakdowns are sparse, a recurring honest limitation for tiny specialties.

  • Women: 41.6% of the training class, 32 of 77 active residents across 33 programs in academic year 2024-25, per ACGME. AAMC publishes no nuclear medicine row, because its specialty dashboard covers only fields with more than 2,500 active physicians, so there is no comparable figure for the practicing workforce; the "around a third" that circulates for practicing nuclear medicine physicians is an estimate with no publisher, and the trainee figure sits well above it.9 ⟳
  • DO: the small applicant pool and historically unfilled positions make the match a realistic target for osteopathic applicants, especially via the direct NM residency.5 The trained class is a separate question and points the other way: 6 of the 77 active residents in AY2024-25 were osteopathic graduates, 7.8%, against 19.6% across all US residents. That is a crowding-out effect rather than a filter, since international graduates take most of the seats, and on an n of 77 one resident moves the share more than a point.10 ⟳
  • IMG: this is the most international field in American graduate medical education. 55 of the 77 active nuclear medicine residents were international graduates, 71.4%, which ACGME's data book ranks first in the country, twenty-one points clear of second-place medical genetics at 50.0% and against 22.7% across all residents. The ABNM also maintains specific pathways for physicians with international nuclear medicine training.4510 ⟳
  • URiM / race-ethnicity: Limited data at the specialty level; consult AAMC workforce reports directly rather than trusting a secondhand number. ⟳

The through-line: a small and aging workforce. The people who trained into nuclear medicine decades ago are retiring, the trained pipeline is thin, and the theranostics wave is arriving on top of that, which is exactly why professional societies frame the field as under-supplied rather than crowded.2

Culture, personality & the online stereotypes

Who gravitates here: people who like physiology and mechanism, the why and how a system is behaving rather than only its picture; those comfortable with physics, chemistry, and quantitation (tracers, half-lives, dosimetry are the daily vocabulary); and increasingly, people who want a reading-room lifestyle with a thread of real oncology-style patient care through the therapy clinic. It draws a quieter, cerebral, detail-oriented temperament, and lately, people specifically excited by being early to a growing therapeutic frontier.

The stereotypes. Community caricatures rather than facts, each with an unfair edge:

  • "The tiny, sleepy, dying specialty." The reputation online for years was that nuclear medicine was a shrinking backwater absorbed into radiology. Reality: theranostics has flipped that narrative hard, and the field is now more often described as undersupplied and growing than dying. The caricature is stale.
  • "It's just radiology's weird cousin." Reality: the overlap with radiology is real (much nuclear imaging is read by radiologists), but the therapy side, prescribing and delivering internal radiation, is a distinct expertise no other field fully owns.
  • "Glorified button-pusher / not real medicine." Reality: dosimetry, eligibility judgment, and radiation-safety responsibility are genuine clinical decisions with real stakes; the therapy side is hands-on patient care.
  • "You'll be replaced by radiologists / by AI." Reality: the authorized-user and therapy roles are legally and practically physician-bound, and the workforce warning is shortage, not surplus.

What people say online (synthesized and paraphrased, not quotes): Across trainee and physician forums, the recurring 2025–26 themes are strikingly two-sided. On the upside: excitement that theranostics is "having a moment", a controllable daytime lifestyle, low competitiveness as a genuine access point, and the appeal of seeing and treating the same disease. On the downside, real and repeated: worry about the small, geographically constrained job market (jobs cluster where there are PET scanners and therapy centers), the radiology-overlap identity question (is it better to just do DR and pick up nuclear along the way?), and uncertainty about whether the theranostics boom will translate into jobs for nuclear-trained physicians specifically or get absorbed by radiology and oncology. The through-line: people who love the science and the growth story, tempered by clear-eyed anxiety about a niche market. Plenty don't fit any mold: the field has both quiet lifers and energized early-adopters. The most common advice to premeds: shadow a theranostics practice, and understand the radiology-vs-direct-NM route decision before you commit.

Voices from the field. Paraphrased from public writing, with links to the originals:

  • Nuclear-medicine leaders writing in the Journal of Nuclear Medicine argue that radiopharmaceutical therapy is growing so fast it risks outrunning the trained workforce, framing expertise rather than technology as the bottleneck.2
  • A multi-continent perspective in the British Journal of Radiology makes the same case globally: theranostics is "taking off," and the urgent question is how to train enough physicians to fill the gap.11
  • Analyses in the Journal of Nuclear Medicine of the 177Lu-PSMA "(r)evolution" weigh, soberly, how much of the hype is materializing in real prostate-cancer care, a useful antidote to pure boosterism.3

Why people choose it / why people leave

Why choose it: you see and treat disease at the molecular level, a rare "diagnose-and-cure" loop · theranostics is a genuine, well-documented growth frontier and you'd be early to it · controllable, largely daytime lifestyle with light acute call · real but manageable patient contact (therapy clinic) without OR or floor life · strong late-career sustainability · comparatively accessible entry, including for DO/IMG applicants · deeply physiological, mechanism-driven intellectual work.

Why leave or avoid it: the job market is small and geographically constrained, and jobs live where PET and therapy centers are · the identity/route question (many reach this work through radiology, which raises "should I just do DR?") · pay is mid-range, not top-tier, and today's surveys don't yet reflect the growth story · a small field means fewer mentors, fewer programs, and thinner data on everything · heavy regulatory/radiation-safety responsibility · if you want broad general-radiology optionality, pure NM is narrower.

Best fit if: you're drawn to physiology, physics, and quantitation · you want a reading-room lifestyle with a thread of hands-on therapeutic patient care · you're excited to be early to a growing field and can tolerate a niche job market · you value daytime hours and career longevity · you're comfortable being the person legally responsible for radioactive materials.

Not for you if: you need a large, geographically flexible job market · you want the broad optionality (and pay ceiling) of full diagnostic radiology · you dislike physics/chemistry-heavy, quantitative work · you want deep longitudinal primary relationships with patients · you'd be uneasy carrying radiation-safety responsibility.

The FLI angle — Nuclear Medicine for first-gen, low-income & immigrant students

Where nuclear medicine fits FLI realities well:

  • A genuinely reachable door. In a landscape where most imaging and procedural fields are tightening, the direct Nuclear Medicine residency is comparatively open, with a small applicant pool, historically unfilled positions, and real accessibility for DO and IMG applicants. For a first-gen or international-trained student without a competitive-specialty pedigree, that's a rare foothold into a physician-scientist-adjacent field.45
  • A relatively fast route. The dedicated NM residency (4 years post-MD: a clinical year, then 36 months) gets you to an attending income faster than the long radiology-plus-fellowship path, which matters if you need to start earning and paying down debt.
  • A growth tailwind you'd be early to. Theranostics is expanding faster than the trained workforce, and being early to an under-supplied field is a form of security that pedigree usually buys, and here the field itself provides some of it.211
  • Controllable lifestyle that supports the caregiving and provider roles many FLI students carry.

Risks to name honestly:

  • The small job market is the real catch. Jobs cluster where the scanners and therapy centers are, largely academic medical centers and larger hospitals in metros. If family, immigration status, or finances tie you to a specific place, a niche specialty with concentrated jobs is a genuine constraint. This is the honest counterweight to the growth story.
  • Mid-range pay, not top-tier. And the theranostics upside is a trajectory, not a number you can bank on graduation day. Plan on the current band, hope for the growth.
  • The route decision matters for FLI students especially. The direct NM path is more accessible but narrower; the radiology path is broader and better-paid but more competitive and longer. Neither is wrong, but choose it with eyes open, because it shapes both your odds and your ceiling.
  • Thin mentorship and data. A small field means fewer people to guide you and less published information to plan against, so you'll have to be more self-directed in seeking out programs and theranostics practices to shadow.

Bottom line: Nuclear medicine is one of the more accessible entries into a physician career with a real, documented growth story attached, a genuine opportunity for FLI students who are drawn to the science and can tolerate a niche, geographically concentrated job market. The theranostics tailwind is real; the small market is the honest risk. Shadow a theranostics practice before you commit, and understand the direct-NM-vs-radiology route decision cold.

Sub-subspecialties & fellowships

Entry into nuclear medicine runs two ways, and the fellowship route is at least as common as the residency one.

  • Nuclear radiology as a fellowship. Many practicing nuclear physicians arrive after a diagnostic radiology residency rather than through a dedicated nuclear medicine residency.
  • Therapy and theranostics is the distinct expertise. Treating with radiopharmaceuticals rather than only imaging with them is the part of the work no other specialty fully owns, and it is where the field's growth has been.
  • The two entries lead to different jobs. A radiology-trained nuclear physician usually keeps reading general studies as well, which changes both the schedule and the market for the post.

Fun facts

  • Nuclear medicine's defining move, imaging function and then treating the same target, is why "theranostics" became the field's rallying word.
  • Radioactive iodine (I-131) has been used to treat thyroid disease since the 1940s, making nuclear medicine one of the earliest fields to deliver targeted internal radiation, decades before the word "theranostics" existed.
  • It's certified by two different boards (ABNM and ABR Nuclear Radiology) and entered through multiple routes, which is unusual structural complexity for such a small specialty.
  • Nuclear physicians are legally "authorized users" of radioactive material under NRC rules, so you can't administer therapies without dedicated radiation-safety training on the order of ~700 hours.
  • The radiopharmaceutical market is projected to grow roughly 7-fold from 2022 to 2028 (~$750M → ~$5.5B), with 80+ new radiopharmaceuticals in the development pipeline.2
  • A V/Q scan, a nuclear lung study, is still a go-to for diagnosing pulmonary embolism when a patient can't get CT contrast, such as with kidney problems or a contrast allergy.

  4. ABNM certification training requirements and multiple entry routes — 36-month dedicated NM residency after a clinical year. The board's own wording is sequential: "Before starting Nuclear Medicine training, all physicians must satisfactorily complete one year of clinical training that includes at least nine months in any specialty that provides direct patient care," and separately, for physicians without other specialty training, "36 months of training at an institution with an ACGME accredited Nuclear Medicine program." Corrected 2026-08-17: this page described the clinical year as folded into the 36 months and put the direct route at ~3 years post-MD and ~11 years from the start of college, in five places including both dashboard rows and the FLI section. The year comes first and is additional, so the figures are 4 and ~12. A reader planning against the old numbers would have been a year short.

It is base-weighted and so runs low against total-compensation surveys, and it is used here for percentile structure rather than for levels. ↩ ↩2

  7. Alternate compensation anchor — $375,421 across all employer types, from Marit Health's self-reported panel of eleven nuclear medicine physicians, updated June 2, 2026 (academic $388,977, non-academic $369,208). MaritHealth, "Nuclear Medicine Physician Salary (2026)," https://www.marithealth.com/o/-/nuclear-medicine-physician/salary ⟳ Corrected 2026-08-17: this footnote presented the figure as "~$376,000 average, from BLS OEWS May 2024 and BLS Employment Projections 2024–2034," and the body attributed it to "BLS-anchored data." Three things fail together. The BLS URL cited, oes291024, is SOC 29-1024, which is Prosthodontists — O*NET gives that occupation a $311,180 median for 2025 — so the link pointed at a dentistry series. There is no nuclear medicine physician wage series for it to have been pointing at instead; the 2018 SOC has no such detailed occupation, and BLS folds these physicians into broader physician categories. And the ~$376,000 is Marit's $375,421, which the footnote's own closing note already said came from the self-reported panel rather than from a benchmark. The BLS attribution and URL are gone, the figure is attributed to Marit with its n in the visible sentence, and the resulting anchor is much weaker than it read before: eleven people, not a national wage survey. On Marit Health: it publishes a panel of self-reported physician salaries, and displays MGMA and AMGA benchmarks beside them that are masked unless you create an account. The figure quoted here comes from the self-reported panel, not from either benchmark. Read it as crowd data: unweighted, n=11, and directional. ↩ ↩2

  8. Burnout proxy — no stable nuclear-medicine-specific figure exists. Diagnostic radiology is the nearest well-measured neighbor. AMA Organizational Biopsy 2025 — nearly 19,000 physician responses across 106 health systems in 38 states — puts Radiology at 45.2% against a 41.9% all-physician average, fifth of the nine specialties it names as most burned out, https://www.ama-assn.org/practice-management/physician-health/these-9-physician-specialties-report-highest-burnout-rates. Corrected 2026-08-17: the dashboard, the body and the wellbeing figure now lead with the AMA row rather than Medscape's 51%. AMA is the instrument this page prefers wherever it publishes a row, because it is free, primary and current, and radiology is one of the roughly fifteen the Organizational Biopsy breaks out. The two baselines are seven points apart and never share a sentence. The Medscape reading kept beside it: radiology 51% against an all-physician average of 49%, Physician Burnout & Depression Report 2024 (n=9,226, fielded July–October 2023). That report is paywalled and returns HTTP 402, so its specialty rows are read through two independent relays that agree on the edition, the instrument and every row: Healthgrades Pro (https://resources.healthgrades.com/pro/the-most-and-least-burned-out-physicians-by-specialty) and Advisory Board (https://www.advisory.com/daily-briefing/2024/01/31/physician-burnout). The ~36% is Medscape's 2022 edition, which used a different instrument; the two years are not comparable and the range is the honest answer. Corrected 2026-08-17: this page called radiology's burnout "mid-pack" in three places. Healthgrades' relay of the 2024 edition prints radiology at 51% inside its "specialties with the highest rates of burnout" list — sixth of the ten named, out of the 26 specialties the report covers. Two points above the average is defensible on the number and not on the table, so the page now gives the comparison rather than the label. This footnote also said three relays and named two. ↩

  9. Percent women — AAMC does not publish a nuclear medicine row, and the reason is a rule rather than an oversight. Its specialty dashboard covers only fields with more than 2,500 active physicians, which excludes nuclear medicine along with most small specialties, so the "roughly a third" for practicing physicians is an estimate carried forward and not a published figure. The trainee share is published, at 41.6%: ACGME, Data Resource Book, Academic Year 2024-2025, whose active-residents-by-sex table gives nuclear medicine 33 programs, 77 residents, 32 women (41.6%), 38 men (49.4%) and 7 not reported (9.1%), https://www.acgme.org/globalassets/pfassets/publicationsbooks/2024-2025_acgme_databook_document.pdf. Corrected 2026-08-17: this footnote and the demographics bullet asserted that no published figure existed to check the estimate against. ACGME publishes the trainee share openly, and this repo already reaches for that table where AAMC has no row — the neurosurgery profile records the same substitution. The ACGME figure is residents rather than practicing physicians, so it does not replace the estimate; it does refute the claim that nothing is published. Across all active physicians, women are 38.7% on 2024 data: AAMC, 2025 Key Findings, https://www.aamc.org/data-reports/data/2025-key-findings. The older by-specialty table, which also has no nuclear medicine line, is AAMC, "Active Physicians by Sex and Specialty," https://web.archive.org/web/20250112142220/https://www.aamc.org/data-reports/workforce/data/active-physicians-sex-specialty-2021. ⟳ ↩

  10. School type of the nuclear medicine training class. ACGME, Data Resource Book, Academic Year 2024-2025, Table C.15 (Number of Active Residents by Specialty and Subspecialty and Medical School Type), https://www.acgme.org/globalassets/pfassets/publicationsbooks/2024-2025_acgme_databook_document.pdf : nuclear medicine, 77 active residents — 55 international graduates (71.4%), 15 US LCME graduates (19.5%), 6 osteopathic graduates (7.8%), 1 Canadian (1.3%). The book's own summary text lists nuclear medicine first among "the specialties with the highest percentage of IMGs," ahead of medical genetics and genomics (50.0%), anatomic and clinical pathology (43.9%) and internal medicine (41.2%). The all-resident comparators are from the same table's TOTAL PIPELINE row: 134,730 residents, 57.7% US LCME, 22.7% international, 19.6% osteopathic. Added 2026-08-17: the demographics section had described DO and IMG access only as a hedge — "similarly more open to international graduates than the competitive imaging/procedural fields" — while ACGME publishes the strongest accessibility figure on this page and ranks the field first in the country for it. The DO half moves the other way once measured, at 7.8% against 19.6% across all residents, so the two bullets no longer say the same thing. ⟳ ↩ ↩2
