ACR Appropriateness Criteria for indolent lung cancer: For patients with slow-growing subsolid nodules or atypical cysts where surveillance is chosen over intervention, imaging follow-up aims to detect changes that alter management, with modality selection guided by accuracy and…
Review: CT/MRI biomarkers optimize TARE planning and HCC response assessment; enhancement-based criteria outperform size-based, LI-RADS TRA v2024 adds non-progressing category, radiomics/body composition metrics prognostic, but need validation.
A variable Vision Transformer (vViT) using CT images, radiomics, and clinical data achieved an AUC of 0.856 for distinguishing low- from high-grade renal tumors, with radiomic features contributing most to the prediction.

Dorsal defect of the patella is a benign, typically asymptomatic developmental variant located at the superolateral margin. Coronal views are key. Confident distinction from osteochondritis dissecans (OCD) avoids unnecessary concern or intervention.
A new review outlines evolving breast cancer screening recommendations, including starting ages, intervals, and supplemental imaging, amid shifting guidelines and ongoing debate among professional societies.
AuntMinnie's Women's Imaging MinnieCast episode 12 covers strategies for educating the public about breast density, its effect on mammography sensitivity, and the role of supplemental screening. The episode discusses how to communicate density information to patients.
Contrast-enhanced mammography (CEM) improves the accuracy of local breast cancer staging compared to mammography alone, with better sensitivity for multifocal and contralateral disease, per a new literature review.
At a European Parliament event, radiologists and nuclear medicine physicians urged policymakers to place imaging at the center of Europe’s Safe Hearts Plan to improve cardiovascular health.
At the ACR 2026 meeting, radiology leaders highlighted new strategic partnerships and emerging innovations aimed at advancing clinical practice and workflow.
