How to comply with CMS's CT radiation dose measure
Inconsistency in CT radiation doses represents a modifiable health risk, and doses can be standardized through auditing and feedback to hospitals and physicians.

ED patients prefer empathetic communication for incidental findings
Incorporating patient preferences into communication may improve understanding and follow-up in addressing incidental findings.
Representative axial fused F-18 FDG-PET/MRI images and corresponding anatomic MRI images from a patient imaged at baseline and after initiation of androgen deprivation therapy are shown. Each row displays a distinct vascular territory. White arrows indicate focal areas of increased tracer uptake within the arterial wall, where spherical volumes of interest (VOIs) were placed for maximum standardized uptake value (SUVmax) measurement. Additional VOIs were placed in the superior vena cava and inferior vena cava for blood-pool activity sampling. SUVmax values from the arterial VOIs were extracted on the corresponding PET images and normalized to the blood-pool mean standardized uptake value to derive the maximum target-to-background ratio.

CT radiation doses have fallen sharply over past decade
By Will Morton
The largest reductions appeared in chest examinations with contrast material, where diagnostic reference levels fell 31%.
July 28, 2026
Bar graphs show comparison of volume CT dose index (CTDIvol) (A) achievable doses (50th percentile) and (B) diagnostic reference levels (75th percentile) between 2014 (see reference 4 by Kanal et al) and 2025 (present study) for 10 common CT examination types performed without contrast (w/o) and with contrast (w/). Across all 10 adult CT examination categories, CTDIvol achievable doses and diagnostic reference levels generally decreased from 2014 to 2025, with the largest reductions for torso examinations (chest; abdomen-pelvis; and combined chest, abdomen, and pelvis), intermediate reductions for neck and cervical spine, and minimal change for head examinations.

ACR rolls out PE-RADS for pulmonary embolism care
By Amerigo Allegretto
The framework outlines grading and suggestions for CT and MRI angiography interpretation.
July 21, 2026
Acute pulmonary embolism (PE) with right ventricle (RV) enlargement and clot-in-transit. PE chest axial CT angiography images demonstrate pulmonary embolus in the right pulmonary artery (white solid arrow), an enlarged RV (dotted arrow), and thrombus transiting through the right atrium (black arrows), PE-RADS 4/RV+/T+. The “4” refers to the PE‑RADS ordinal category for the most proximal clot location (central arteries). “RV+” indicates RV enlargement (RV to left ventricle ratio ≥ 1.0). “T+” indicates definitive thrombus identified in the right atrium and/or RV.
