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…
AI models detect acute Type A aortic dissection on CT with AUC 0.86 to 0.99 and sensitivity 91% to 97%, but direct evidence that they reduce door-to-surgery time or mortality is lacking. Simulated workflows cut report times 26% to 43%.
Multiparametric MRI with VI-RADS reliably separates muscle-invasive from non-muscle-invasive bladder cancer, but clinical utility hinges on quality control, reducing reader variability, and integrating AI—this review covers implementation, post-treatment response, and AI solutio…

Multimodal ML model integrating CT radiomics and clinical features predicted ILD with AUC 0.715 (95% CI 0.661–0.770) on external validation (614 patients) and 0.733 on internal validation.
An 81-expert Chinese panel reached consensus (scores 8.06–8.58 on 9-point scale) on 30 statements covering AI applications from cancer screening to post-deployment surveillance. Recommendations include expert-supervised labeling, multicenter validation, interpretable outputs, an…
Graph-based white matter tractometry preserves spatial topology and detects distributed pathology patterns. A systematic maturity assessment finds modest improvements over traditional methods, but comprehensive benchmarking against TBSS and AFQ is absent, and validation platform…
A review proposes a shift from FDG-PET to multimodal molecular-structural fusion using novel PET tracers targeting synaptic density, neuroinflammation, and neurotransmitter systems, integrated with isotropic 3D MRI and AI coregistration, to improve surgical localization of epile…
A Vision Transformer-based nomogram using serial grayscale ultrasound images predicted 3-year graft-related adverse event-free survival with an AUC of 0.831 in external validation, outperforming a clinical model (AUC 0.808, p=0.048). A hepatic artery resistive index <0.55 within…
In 60 brain tumor patients, a new fluid-suppressed diffusivity map outperformed ADC for visualizing reduced diffusion, and was significantly linked to IDH status.
In pleomorphic xanthoastrocytoma, VASARI MRI features—diffusion restriction (HR 5.10), midline crossing (HR 3.82), mixed cystic-solid morphology (HR 3.42)—predicted recurrence. Optimism-corrected C-index 0.79 (95% CI 0.70–0.86).
After thrombectomy with emergent carotid stenting for tandem lesions, recurrent systolic blood pressure peaks >140 mm Hg independently predicted symptomatic intracranial hemorrhage (sICH) in patients without known hypertension (adjusted OR, 7.45; 95% CI, 1.39-39.79), a multicent…
A combined radiomics and Vision Transformer (ViT) model using CT threshold segmentation predicted visceral pleural invasion in lung adenocarcinoma ≤30 mm with AUCs 0.895 training, 0.852 internal test, 0.823 external test, and the highest sensitivity.
For radiographic knee OA grading, ChatGPT-5.0 outperforms GPT-4o but remains inferior to clinicians. Binary detection sensitivity 0.96 but specificity limited. Not suitable for standalone assessment.
In 6700 stroke patients, direct aspiration first-pass thrombectomy (ADAPT) achieved higher first-pass effect without symptomatic hemorrhage than stent retriever (39.9% vs 26.9%; aOR 2.07). ML identified subgroups with greater benefit: recent years, M1 occlusions, earlier time wi…
O-RADS ultrasound v2022 had AUC 0.935, sensitivity 98.3%, specificity 70.8% for adnexal mass malignancy (threshold ≥ category 4). Performance comparable to v2019 and ADNEX model, with numerically higher specificity and greater reader agreement.
