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…
For distinguishing true progression from pseudoprogression in glioblastoma, radio-pathomic cell density (RPM Cell) maps achieved an AUC of 0.827, significantly outperforming advanced diffusion and perfusion metrics (AUCs <0.687, p=0.006).
In 390 cirrhotic patients with sarcopenia undergoing TIPS, sarcopenia reversal at 1 month (48.2%) was associated with higher survival (84.6% vs 68.2%; HR 0.24) and lower OHE (16.6% vs 51.1%; HR 0.26). PMI improvement rate was an independent predictor; optimal cutoffs >11.8% for…
Spinal Cord Injury Following Two-Stage Embolization and Cryoablation for a Cervical Aneurysmal Bone Cyst: Mechanism, Thermal Characterization, and Practice Recommendations.
Automated CT volumetry of peripancreatic collections predicts organ failure (AUC 0.82 vs mCTSI 0.73) and infection (AUC 0.79 vs 0.72) in acute pancreatitis, 25.2s vs 12.4min per patient.
In an exploratory reader study of AI overlays for pediatric whole-body MRI, AI assistance increased evaluation time for both radiologists but had mixed effects on the number of candidate lesions marked: one radiologist marked more, the other fewer. Both reported lower stress wit…
Cross-sectional OAI study (n=4,257): larger DL-derived infrapatellar fat pad volume on MRI associated with greater patellofemoral cartilage thickness (+0.011 mm/cm³) and less cartilage damage, BMELL, and meniscal tears in lateral compartments.
In a review of 46 interval DBT cancers, 17% were missed (false negative). AI correctly identified 35%, but only 22% of cancers with high mammographic visibility, suggesting about 20% of interval cancers could be diagnosed earlier using AI.
In 176 healthy adults aged 68-85, longitudinal MRI clustering identified two groups: one with minimal atrophy and one with more pronounced left prefrontal/central atrophy. The atrophic cluster was linked to lower education and trended with cognitive decline.
From detection to clinical practice: Defining acceptable false-positive thresholds for pre-diagnostic pancreatic cancer detection.

Medicine is better viewed as avoiding unforced errors than chasing rare diagnoses, especially in radiology where images are permanent. Search patterns build consistency and reduce mistakes.
A multisociety coalition released a radiation safety toolkit for interventional fluoroscopy, aiming to curb occupational health crisis. Survey found nearly 60% of clinicians reported orthopedic injuries from lead aprons, and 1 in 5 reduced caseload or took leave.
OhioHealth is investing $10.2 million to double CT scanner capacity at its Bradley Cancer Center in Circleville, Ohio, adding a second scanner to the only facility offering CT in Pickaway County. The two-year project also adds five infusion spaces and expands pharmacy services.
