In 82,957 women with negative screening mammograms (Kaiser Permanente cohort), combining Mirai AI, a 313-SNP polygenic score, and BCSCv3 clinical risk reached C-index 0.70 (95% CI 0.69–0.71) vs 0.66, 0.62, and 0.61 for each alone — supporting integrated risk-stratified screening.
After venous sinus stenting for pulsatile tinnitus, temporal bone remodeling occurred in 73.1% of patients with follow-up CT (38/52). Remodeling was significantly more likely with a diverticulum vs isolated wall dehiscence (85.7% vs 47.1%; adjusted OR 8.08, 95% CI 1.31-49.73), a…
Across >3 million multicenter emergency department encounters, overall ED neuroimaging utilization doubled from 2016 to 2025. Head CT without contrast remained dominant, but CT perfusion use rose >5-fold over the same period, signaling a marked shift in acute stroke workup inten…
Pulling a chest X-ray AI triage tool caused both operational relief and perceived clinical loss among NHS radiology staff. Post-decommissioning, 70% still saw patient benefit (vs 71% pre-implementation), but logistical burden rose vs late-use. Authors propose a 3-phase off-board…
A prospective study shows Hologic's AI-based workflow tool maintains screening mammography accuracy while significantly reducing time to review prior exams, potentially easing radiologist workload without compromising performance (exact figures not reported in source).
Interventional radiologist Maureen Kohi, MD discusses navigating the 'double bind' facing women in medicine, overcoming self-doubt, and building authentic leadership identity — practical career guidance for residents through attendings.
A new educational lecture argues that ‘transient osteoporosis of the hip’ is a misnomer; modern MRI reveals these cases are actually subchondral insufficiency fractures invisible on older scanners.
The European Society of Radiology releases a new set of procedural video resources (A, B, C) for neuro-intervention education. No primary research findings; content appears to be technique-focused teaching material for trainees and practitioners.
The European Society of Radiology releases a new set of three procedural videos (A, B, C) in its neuro-intervention educational series, page 54. Specific techniques or cases covered are not detailed in the source.

ACR Appropriateness Criteria for pediatric GI bleeding: CTA abdomen/pelvis is usually appropriate first-line imaging in unstable patients; nuclear medicine (Meckel scan, tagged RBC) aids localization; many benign cases need no imaging at all.
ACR Appropriateness Criteria for epigastric pain updated: evidence-based imaging recommendations now cover esophageal/gastroduodenal perforation, GERD, esophagitis, peptic ulcer disease, hiatal hernia, and post-reflux surgery scenarios, using GRADE methodology.
CTisus hosts a Facebook Live discussion on leadership insights from outside medicine, part of their 2025-26 speaker series. The conversation reflects on key takeaways for radiologists. Full videos on YouTube.
Complete ulnar styloid attachment tear of the TFCC leaves the bony footprint empty due to tendon retraction. Look for subchondral cyst formation and lunotriquetral ligament injury as secondary signs of instability.
The Office of Management and Budget released a proposed rule on federal financial assistance. The American College of Radiology is reviewing its potential effects on radiology practices (details not yet reported).
A new PET imaging method may improve monitoring of cancer treatment response, per a trade news report. Details on clinical accuracy, patient numbers, or validation were not provided.
RSNA news piece urges embedding sustainability into cancer imaging and care, aiming to reduce environmental footprint while preserving high-quality patient outcomes.
A new radiology teaching case from CTisus asks 'What is the most likely diagnosis?' — a quick-fire CT quiz to test and sharpen diagnostic reasoning, especially useful for trainees reviewing call-level cases.
At SNMMI 2026 in Los Angeles, theranostics dominated scientific sessions with new agent data, while non-FDG PET radiotracers signal a broadening diagnostic landscape. Specific efficacy or trial numbers not reported in source.

Combined radiomic-clinical XGBoost model achieved AUC 0.897 on test set for separating pulmonary TB from pneumococcal pneumonia in children — outperforming clinical-only (AUC 0.784) and radiomic-only (AUC 0.865) models. Single-center, small n; not yet externally validated.
SCCT and SCAI (endorsed by ACC) release expert consensus on CT-derived fractional flow reserve (FFR-CT): appropriate use, patient selection, reporting, and integration with coronary CT angiography workflows. Provides field-wide standardization where formal guidelines were absent.
A JACR paper challenges studies that validate head CT reformatting techniques against AI output rather than a true ground truth — arguing this measures AI agreement, not diagnostic accuracy. Methodological distinction matters for interpreting such literature.
C-TIRADS ≥4B yielded 75.7% sensitivity, 75.8% specificity (AUC 0.784) for thyroid malignancy—not significantly different from Kwak TI-RADS (P>0.05) in 272 surgically confirmed cases (retrospective).
Signify Research is updating its subscriber portal homepage to a new layout from 1 July 2026. The change is purely a user-interface refresh — no new content or data offerings were announced in the notice.
Radiologist-entrepreneur Paul Chang, MD, offers practical advice on identifying clinical pain points and channeling them into healthcare innovation, in a new RSNA Unscripted episode aimed at aspiring radiology innovators.
