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 model using multi-view 2D echo (no Doppler) classified LVOT obstruction (>20 mm Hg) in hypertrophic cardiomyopathy with external validation AUC 0.84. Enables scalable, cost-effective screening.
Cerebrovascular reactivity can be estimated from resting-state BOLD fMRI without a breath-hold or gas challenge. The reconstruction method achieved a mean spatial correlation of 0.61 with hypercapnic CVR maps (0.72 in high respiratory variability).
Critical dialogue: Interstitial lung abnormalities: an evolving concept.
In a meta-analysis of 30 test datasets (67,266 non-contrast CTs), U-Net deep learning models had higher sensitivity (0.916) and precision (0.983) for subdural hematoma detection vs other architectures. However, only 4 U-Net datasets were pooled vs 22 for CNN, so conclusions are…
Correction: Diagnostic accuracy of deep learning vs. human raters for detecting osteoporotic vertebral compression fractures in routine CT scans.
Bibliometric analysis of CT use in human identification shows growing scientific output since 2015, with most studies assessing age and sex; Japan leads in citation impact. No significant link found between journal impact factor and citations.
A deep learning model detected simulated external root resorption with 100% accuracy on periapical radiographs and up to 97.92% on CBCT. Performance dropped to 73.96% with three-dimensional reconstruction, especially in treated teeth.
Optical tissue sensing during vacuum-assisted breast biopsy distinguished malignant from healthy tissue with 86% accuracy, 91% sensitivity, 82% specificity in ex vivo study of 40 mastectomy specimens.
In 183 patients with chronic limb-threatening ischemia, a Small Artery Disease (SAD) score ≥1 on lateral foot DSA increased risk of major adverse limb events (HR 2.22, p=0.011) and death (HR 2.06, p=0.025), but not wound healing or amputation.
Delayed Inferior Thyroid Artery Pseudoaneurysm and Arteriovenous Fistula after Microwave Ablation of a Benign Thyroid Nodule.
Percutaneous Gun-sight Reentry from an Occluded Femoral-Popliteal Bypass Stump to the Native Superficial Femoral Artery for Limb Salvage.
LLMs significantly improved radiology report readability (P<0.05), with DeepSeek-R1 performing best, but all models showed inherent output instability and information omission. Optimized structured prompts reduced model variance and improved translational accuracy, particularly…
A prospective, 21-site, two-vendor study (FAST-CMR) will evaluate a free-running, non-ECG-gated cardiac MRI framework (5D FISS-FRF) in 300 patients with cardiac disease, comparing LVEF precision to conventional cine.
DenseNet121 model classified cochlear implant electrode position on X-rays with an AUC of 0.932 (95% CI 0.836–1.000) and 98.6% specificity, with interpretable attention maps.
In 530 acute ischemic stroke patients, the automated DWI biomarker SCR-U1.8 logistic regression model achieved 0.990 accuracy and 0.998 AUC for predicting malignant cerebral edema, though only 12 events occurred; findings are exploratory and require external validation.
A study in 972 men externally validated the PROMOD biopsy strategy. PI-RADS 4-5 or PI-RADS 3 with a PSA density >0.15 avoided 18-20% of biopsies while missing 5-8% of clinically significant cancers. A more conservative approach (PI-RADS 4-5 or PI-RADS 3 with PSA density >0.10) a…
