ASFNR clinical state-of-practice: For posterior circulation large vessel occlusion stroke, use noncontrast CT to exclude hemorrhage, CT angiography to identify occlusion, and MRI with DWI as reference standard. Imaging scores like PC-ASPECTS help select patients for thrombectomy.
The ACR Appropriateness Criteria 2026 update provides imaging guidelines for suspected or confirmed diffuse lung disease, covering initial evaluation, acute exacerbation, and surveillance.
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…
Transcatheter genicular artery embolization provided durable pain reduction in patients with moderate-to-severe knee osteoarthritis: mean pain scores dropped from 8.1 to 2.5 at 36 months and WOMAC scores improved markedly (exact figure not reported in source).
A new four-year curriculum aims to train Malawi's first MRI radiologists, addressing the country's critical shortage of imaging expertise. The program, reported by RSNA, will build local capacity for MRI interpretation and service delivery.
Crescom and Mass General Brigham have launched a clinical validation study for an AI tool targeting pediatric musculoskeletal imaging. Study design, endpoints, and timeline were not disclosed, and no performance data are yet available.
New FFR-CT techniques enhance non-invasive detection of hemodynamically significant coronary stenosis, potentially reducing diagnostic catheterizations. Recent refinements include improved computational fluid dynamics and integration with photon-counting CT, though exact sensiti…
A new study found that prunes are not likely to improve bone health in men, contrasting with some prior data in women. (Exact figures not reported in source.)
Study examines whether AI can match radiologists' sensitivity on breast ultrasound for pregnant/lactating women. Exact performance metrics not disclosed in source.
Mass General Brigham Radiology has begun clinical validation of an AI tool for musculoskeletal imaging developed by Crescom. No performance metrics or clinical outcomes have been reported yet; the validation is ongoing.
The American College of Radiology (ACR) now offers reports from its General Radiology Improvement Database (GRID) to facilities participating in the National Radiology Data Registry (NRDR), enabling benchmarking and quality improvement.

Multi-center AI (45,139 ultrasound images, 9,215 fetuses, 22 hospitals) detected fetal orofacial clefts with sensitivity >93% and specificity >95%, matching senior radiologists. Used as a copilot, it raised junior radiologists' sensitivity by >6 percentage points.
In 3 datasets, the Weighted Gain Score (WGS) correlated strongly with Rasch Learning Gain (r=0.93 empirical, r=0.92 simulated; both P<.001). Varying the µ calibration parameter shifted estimate magnitude but left inferential conclusions unchanged — suggesting WGS is a simpler, v…
This paper examines a Philosophy for Children curriculum in out-of-school settings on preschool executive functioning (n=37). Experimental group scored higher than controls (52.59 vs 32.85, η²=0.94, p<0.05). Content has no radiology relevance; likely misfiled in this feed.
Economic model of femoropopliteal peripheral artery disease treatment: paclitaxel drug-coated balloons averaged $8,406/patient over 3 years vs. $9,151 for angioplasty alone — cost-saving. Bare-metal stents ($13,325) and drug-eluting stents ($13,054) exceeded $150,000/QALY, faili…
A new review argues that clinical obesity imaging should transition from simple adiposity confirmation to integrated body composition phenotyping using CT/MRI biomarkers to guide personalized risk assessment and therapy. (exact figures not reported in source)
Increasing test-time compute ("reasoning effort") can meaningfully change large language model performance on radiology tasks, yet most studies fail to report or control for this budget variable, risking non-reproducible results.
AI-based denoising in coronary CTA can reduce radiation dose by 80% while maintaining comparable image quality to standard-dose exams, though objective image noise was higher. The ultra-low-dose protocol averaged 0.96 mSv.
QSM-only deep learning detected paramagnetic rim lesions in MS with 72.4% sensitivity (vs 62.1% for QSM+FLAIR) on internal test; automated PRL burden linked to cognitive impairment (p=0.002). Retrospective study.
The FDA has cleared Siemens' myAblation Guide (VC10A), an image-guided ablation system for interventional radiology (product code QTZ).
FDA granted 510(k) clearance to Siemens Medical Solutions for its ACUSON Sequoia, Sequoia Select, Origin, and Origin ICE diagnostic ultrasound systems (product code IYN). The clearance permits U.S. marketing of these general imaging platforms.
Score-based generative diffusion models synthesized full-dose FDG brain PET from MRI alone with the lowest whole-brain SUVR error and highest ICC, improving further when ultralow-dose PET was added, in a retrospective study of 52 epilepsy patients.
Retrospective machine learning analysis of IVIM diffusion MRI predicted amyloid status with 80% accuracy and correlated with amyloid (r=0.53), tau (r=0.61), and cognitive decline (r=-0.60) in 94 aging individuals (45 Aβ+).
An interprofessional education (IPE) model for geriatric oral health, built on the “4Ms” Age-Friendly framework and Kirkpatrick evaluation, is advocated to replace siloed training—a structure that could be adapted for radiology’s aging patient care.
Dense breast categorization rose from 38.4% to 39.1% (p=0.01) after Breast Imaging Reporting and Data System (BI-RADS) 5th edition, with negligible practical effect size (Phi=0.01), in a single-institution study of 132,326 mammograms.
A pilot case-based radiology curriculum boosted Year 3 medical students' chest X-ray interpretation confidence from 3.1 to 7.6 (mean diff 4.5, p<0.001) and radiation dose awareness from 38% to 81%. 88% preferred case-based teaching.
Higher systemic immune-inflammatory index (SII) was associated with malignancy in Lung-RADS 4 lung nodules on LDCT: adjusted difference +272 (95%CI 75-470, P=0.007) and OR 3.74 for SII >561.
