The opinion manuscript discusses the challenges in estimating the pediatric radiology workforce and access to care in the U.S. It highlights the significant role of children’s hospitals in delivering specialized care but notes the geographic and workforce distribution disparities. The study finds that while children’s hospitals are essential, they are geographically concentrated, and pediatric radiologists are often spread thin, with many working remotely via teleradiology.

The objective of this study it to estimate the share of the Medicare fee-for-service population with sarcopenia compared with osteoporosis, an associated age-related disease, using claims data and to assess abdominal CT use in the diagnosis of sarcopenia compared with dual-energy x-ray absorptiometry for the diagnosis of osteoporosis Full Article

Imaging self-interpretation refers to interpretation of an imaging study by the study's ordering provider. This phenomenon warrants scrutiny given nonradiologists' limited training in imaging interpretation. The objective of this study is to evaluate the frequency of self-interpretation of office-based diagnostic imaging by ordering providers and to assess associations of ordering provider and practice characteristics with self-interpretation, within-practice interpretation, and radiologist interpretation.

Diagnostic imaging interpretations by nonphysician practitioners (NPPs) are increasing. With hospital-based imaging overwhelmingly interpreted by radiologists, the researchers studied office-based interpretations by NPPs by their physician employer specialty. View Infographic
