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…
An nnU-Net tool (DORES) segmented enlarged perivascular spaces on brain MRI, achieving Dice scores of 0.61 (white matter) and 0.72 (basal ganglia) in a development cohort, with modest decline on external data and scanner-dependent variability.
Noncontrast abdominopelvic CT with silver filter + deep learning reconstruction cuts radiation dose by 36% (p≤0.05) without image quality loss; HU values significantly lower for urine (38%) and subcutaneous fat, relevant for cyst/adrenal evaluation.
Medicare Graduate Medical Education Funding and Radiology Residency Growth: Trends and Implications for Workforce Policy.
Every 10-case increase in mechanical thrombectomy volume for acute ischemic stroke was associated with a 1.2% reduction in odds of mortality (OR 0.988, 95% CI 0.980–0.995, p=0.001). However, cardiac and pulmonary complications remain common, affecting 40.5% and 30.5% of patients.
Improvement in lower urinary tract symptoms after PAE was associated with erectile function improvement (partial r= -0.25 at 12 months; P=.020), particularly in men with baseline erectile dysfunction (partial r= -0.38; P=.008). Strong urinary responders more often met the minima…
Catheter-Associated Tumor Thrombus: A Consideration Beyond Bland Thrombus and Fibrin Sheath.
AI models for tasks like caries detection and lesion segmentation on dental X-rays and cone-beam CT show promise, but current studies are mostly retrospective and single-center, lacking external validation and standardized datasets needed for clinical adoption.
For multiple sclerosis imaging, 3D-EPI with CAIPIRINHA and deep learning denoising provided 0.65 mm whole-brain T2* in 1 min 56 s; denoising increased PSNR by 3 dB, SSIM by 13%, and lesion-to-vein contrast by 9%.
A CycleGAN model trained on real ultra-low-field and high-field MRI improved hippocampal volume agreement and brain segmentation accuracy, with better test-retest reproducibility than direct ULF segmentation.
An AI-assisted decision-support model using patient-level variables reduced categorization disagreement by 26% for breast density and background parenchymal enhancement on contrast-enhanced mammography, achieving AUC 0.75, precision 0.72, and recall 0.69, with greatest benefit i…
Best semi-supervised and transfer learning methods achieved Dice 0.89 vs fully supervised 0.92 for kidney segmentation on non-contrast MRI, substantially reducing need for manual annotations.
In MDD, putamen-centered functional connectivity disruptions were key discriminators. Multimodal MRI model (volumes+FC) classified patients vs controls with AUC 0.685 and 65.3% accuracy.
A review highlights recent cardiac MRI advances—higher-resolution imaging, refined parametric mapping, 4D flow, novel gadolinium alternatives, and AI integration—that improve diagnostic accuracy and workflow, though cost and patient tolerance remain challenges.
Combining cfDNA tumor mutation burden and gene mutation score with age and BI-RADS classification yielded an AUC of 0.923, 88.1% sensitivity, 89.1% specificity for predicting malignancy in 212 patients with BI-RADS 4 breast nodules.
A logistic regression model using age, prostate health index (PHI), and PHI density (PHID) predicted clinically significant prostate cancer in men with PI-RADS 3 lesions with an AUROC of 0.840 (95% CI: 0.754–0.916) on internal validation.
