Radiologist Workforce Growth Trails Behind Rising Healthcare Demand

A recent study published in the Journal of the American College of Radiology (JACR) highlights a concerning trend in the U.S. radiology sector: the growth of radiologists practicing in the field is not keeping pace with the overall demand for medical imaging. Despite an increase in radiology training programs and positions over the past 15 years, the number of active radiologists has only modestly increased.

Researchers used four national datasets to evaluate the trends in radiology training and the active radiologist workforce from 2010 to 2025. Their findings reveal that while radiology residency slots grew by 33% and resident numbers by 23% by 2024, the practicing radiologist count rose only by 12% from 2010 to 2022. This translates to a minimal increase from 11.1 to 11.5 radiologists per 100,000 people.

The study points out that radiology's growth is outpaced by the medical field at large. From 2002 to 2025, radiology positions expanded by 66%, whereas the total across all medical specialties was 89%. Professor Ajay Malhotra from Yale School of Medicine emphasizes that despite more trainees entering the field, the expanding population and attrition rates in radiology have absorbed the gains, compounded by an aging population driving increased imaging demand.

"The radiologist pipeline has grown, but almost none of that growth has reached patients," said Malhotra. "After accounting for population growth, the number of radiologists per person is essentially where it was fifteen years ago, and that is before you factor in an aging population that uses more imaging per capita."

This stagnation in the number of practicing radiologists per capita presents challenges for timely diagnosis and treatment, as well as for individuals awaiting imaging results. The findings underscore the need for strategies to enhance the radiology workforce further and address the rising demand for imaging services due to demographic changes.
