Radiology pipeline expanding slower than medicine

The American College of Radiology said on September 2 that U.S. demand for medical imaging is rising faster than the radiologist workforce. The finding comes from a new study in the Journal of the American College of Radiology that tracked residency positions, residents in training and practicing radiologists over more than two decades. MedicalXpress and News-Medical, citing the study, reported that the specialty’s training pipeline has expanded, but not enough to keep pace with population growth and broader growth across medicine. The result is a narrower increase in radiologists available per capita even as imaging remains central to diagnosis and treatment. ### How much did the radiology pipeline actually grow? The JACR study said radiology residency positions grew 33% from 2010 to 2025. The total number of radiology residents increased 23% through 2024, according to the summaries published by MedicalXpress and News-Medical. Practicing radiologists, however, increased only 12% between 2010 and 2022. (medicalxpress.com) The same study found the per-capita supply barely moved. The number of radiologists in practice rose from 11.1 per 100,000 people in 2010 to 11.5 per 100,000 in 2022, according to the reports. That gap between training growth and practicing supply is the central measure behind the workforce concern. ### How does radiology compare with medicine overall? (medicalxpress.com) From 2002 to 2025, radiology positions grew 66% across the specialty, compared with 89% across all specialties, according to MedicalXpress’ summary of the paper. The JACR abstract similarly said the radiologist pipeline has grown but lags overall residency expansion and population needs. (medicalxpress.com) The American College of Radiology has described the issue in similar terms in other 2026 publications. In an April bulletin article, the group said imaging volumes continue to rise while the workforce pipeline expands slowly, and said practices are dealing with pressure on how radiology work is designed and supported. (medicalxpress.com) ### What is driving the pressure on radiology practices? Medical imaging has become embedded in more clinical pathways, and ACR officials have said that volume growth is colliding with limited staffing. In a March bulletin article, ACR Board of Chancellors Chair Alan H. Matsumoto said international medical graduates could help practices facing high volume and a thin workforce. (acr.org) Other recent JACR-related reporting has pointed to operational strain around turnaround times. MedicalXpress reported in April that time to imaging results had doubled since 2014, and another August report said turnaround times continued to increase across modalities through 2024. Those studies are separate from the new pipeline paper, but they describe the same setting of rising workload and constrained capacity. (acr.org) ### Why does this matter beyond radiology? Radiology sits near the center of hospital and outpatient workflows because imaging is used across emergency care, cancer care, surgery and routine diagnosis. ACR Commission on Economics Chair Lauren P. Nicola wrote in June that nearly every clinical pathway depends on imaging and that the specialty faces sustained economic strain. (medicalxpress.com) The new study does not forecast a specific shortage date, but it documents a measurable mismatch between demand growth and workforce growth. For health systems, that makes radiology one of the clearest specialties to watch when assessing staffing, training capacity and workflow design under pressure. That is an inference based on the study’s data and ACR’s own workforce descriptions. (acr.org) ### Where can readers find the underlying evidence? The Journal of the American College of Radiology published the study, titled “The Evolving US Radiologist Pipeline: Trends in Residency Positions...,” in 2026. The American College of Radiology amplified the findings on September 2 through coverage carried by News-Medical, while MedicalXpress published a separate summary the same day. (acr.org) The next public reference points are likely to come from JACR follow-up research and ACR workforce publications. ACR’s 2026 bulletin pages on workforce economics and access to care remain the named venues where the group has been updating members on staffing pressure, hiring constraints and training capacity.
