A new study from HPI found that attrition (i.e., exit) from the radiology workforce increased for all subspecialties, but with varying magnitude. The study, published in AJR, was based on all Medicare radiologists who submitted claims between 2014 and 2022 and covered 159,490 radiologist-year observations for 29,770 radiologists practicing as subspecialists.

A new study from the HPI found that the time between an imaging scan and its interpretation for office/hospital outpatient imaging increased 113% between 2014 and 2023, with most of this increase occurring in 2022 and 2023. The study, published in the JACR, was based on claims for 2.6 million office/hospital outpatient imaging studies. Read More
A new study from the Neiman Institute found that practice turnover among radiologists increased 61% between 2013 and 2022. The study also found that turnover rates differed by gender, practice location, academic status, workload, and years of practice. The study, published in the Journal of the American College of Radiology, was based on 39,439 radiologists covering 280,692 practice years between 2013 and 2022. Read More
A new Neiman Institute study , performed with the American College of Radiology’s Pediatric Imaging Research Committee, highlights differences in imaging use among children that raise safety concerns and opportunities to reduce radiation exposure. The study analyzed over 5.4 million outpatient hospital encounters for pediatric Medicaid patients and found significant differences in imaging utilization between children’s hospitals and non‑children’s hospitals.

A new study published in JAMA Network Open highlights the significant environmental footprint of medical imaging contrast agents, finding that Medicare patients alone received 13.5 billion milliliters of contrast media between 2011 and 2024. Conducted by a team of researchers, the study underscores the urgent need to address the environmental impact of these widely used diagnostic materials. Read More
