New expert consensus framework for symptomatic B3 breast lesions: assess concordance, lower excision threshold for discordant/palpable lesions, conservative management for concordant non-atypical lesions, and risk-based surveillance for atypia.
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…
In CT harmonization, CycleGAN and diffusion models caused -100% volume errors in adipose tissue segmentation, while a Gaussian filter had minimal error, showing task-specific validation trumps visual metrics.
In a meta-analysis of 37 studies (95,148 femur images), AI detection of traumatic femur fractures had pooled sensitivity 0.94, specificity 0.94, AUC 0.98—similar to human experts (0.91, 0.93, 0.97). AI augmentation raised non-expert AUC from 0.95 to 0.97.
A review finds joint representations linking cardiac CT, MRI, and echo to bulk, single-cell, and spatial transcriptomics are advancing through spatial multiomic maps and foundation models, but cost, scalability, and tissue availability limit large-scale translation.

The American College of Radiology (ACR) has published a news item.
Butterfly Network has launched its handheld, whole-body ultrasound devices in Brazil, expanding point-of-care imaging access in Latin America. (News announcement; primary source not reviewed.)
Published VAPOR 2 trial data evaluate water vapor ablation for localized prostate cancer; the procedure may offer a minimally invasive option, but specific outcomes and numbers are not reported in this news source.
Current coronary plaque volume, measured by CCTA, was a better predictor of major adverse cardiac events than baseline or cumulative plaque burden, suggesting a dynamic measure is key to risk assessment.

High cost-sharing for imaging in some Medicare Advantage plans may create barriers to care, warns a study in AJR. (Details not provided).
Homeland Security warns that vulnerabilities in medical imaging software could allow attackers to write unauthorized files, access sensitive data, or crash client servers.
VCU has opened a $30 million research imaging center dedicated to liver disease, aiming to develop new imaging-based treatments for millions affected by these conditions.
A new study in Clinical Radiology compared full-field digital mammography, digital breast tomosynthesis, and breast MRI for early breast cancer detection and identified a superior modality (specific results not reported in this source).
A stacking ML model using 3DCT pelvic measurements achieved up to 96.1% accuracy for sex estimation in Black South Africans, outperforming traditional methods. Cranial measurements reached 94.3%. Retrospective, single-center, not externally validated.
Combining anatomical location and ADC threshold for transition zone PI-RADS 3 lesions avoided 62% of biopsies while detecting 91% of clinically significant cancers, in a retrospective study of 218 lesions.
In 29,339 pts, fully automated AI-derived aortic size index from MPI CT attenuation correction scans predicted all-cause mortality: ascending >2.2 cm/m2 HR 1.16 (1.07-1.26), descending >1.6 cm/m2 HR 1.23 (1.14-1.31), independent of perfusion defects.
In a Korean bronchiectasis cohort (n=492), blood eosinophil count showed no significant association with acute exacerbations or disease severity. Instead, oral corticosteroid use (IRR 2.26, 95%CI 1.46-3.52), older age, and lower FEV1 were independent risk factors.
