Current Challenges in Estimating the Pediatric Radiology Workforce and Access to Pediatric Radiology Care in the United States

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.

Self-Interpretation of Imaging Studies by Ordering Providers: Frequency and Associated Provider and Practice Characteristics

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.

Excess Greenhouse Gas Emissions Associated With Inappropriate Medical Imaging in the US Medicare Part B Population From 2017 to 2021

Medical imaging is a source of greenhouse gas emissions, and inappropriate use results in low-value, excess imaging. The environmental impact of low-value imaging has not been quantified. Full Article

Opportunistic screening for osteoporosis: validation study for L1 bone density measurements using contrast-enhanced chest and abdominal CTs

To retrospectively validate the diagnostic power of attenuation values on chest and abdomen/pelvis CECTs, together and separately, compared with dual-energy X-ray absorptiometry (DEXA)-determined osteoporosis diagnoses, and to determine thresholds for accurate osteoporosis diagnosis. Full Article
