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.

Tau PET tracer flags early Alzheimer risk in healthy older adults

Few studies have investigated how F-18 PI-2620 is associated with memory performance or AD-related biomarkers in cognitively unimpaired older adults.

F-18 PI-2620 average binding potential maps. Mean tracer binding (DVR) image from 165 older adults (A) and 13 young adults (B). Images are scaled from 1 to 1.8 for display purposes, but DVR values of less than 1 were frequently observed.

Radiologists can identify three out of four AI-generated images

By Amerigo Allegretto

Radiologists found it particularly difficult to distinguish between real and AI-generated CT and MR images.

July 17, 2026

Top eight incorrectly classified synthetic images (Most convincing fake images). Images A, B, C, D, E, F, G and H were the most infrequently correctly classified images at 24%, 43%, 59%, 64%, 69%, 71%, 71% and 73% respectively. All images are AI-generated. Images A, B and C are head CTs. Images D and E are chest CTs. Image F is a cardiac CT. Image G is a musculoskeletal MRI. Image H is a head MRI.
