Individualized post-trigger delay for pancreatic CT yielded higher attenuation (head 126 vs 86 HU, p<0.001; body 125 vs 93 HU) and better subjective quality (84% vs 30% excellent/good) in a prospective 100-patient study.
Integrating artificial intelligence readiness into radiology curricula is now an educational obligation, according to a new perspective. Training programs must prepare residents for AI-augmented practice to meet evolving clinical demands.
Bayesian Beta-Binomial model showed improved robustness and lower estimation error vs classical linear models in MRMC studies with overdispersion and small sample sizes, applied to chest X-ray bone suppression imaging.
Over 20 years, interventional radiology evolved from a palliative adjunct to a core component of multidisciplinary thoracic oncology, using CT-guided navigational biopsies, thermal ablation for nonsurgical lung cancer, embolization for hemoptysis, and growing pleural interventio…
This review defines complementary roles of MRI/MRCP and endoscopic ultrasound (EUS) in pancreatobiliary disease. EUS is problem-solving when MRI is equivocal, enabling tissue acquisition, molecular testing, and interventions. A clinically driven selective imaging pathway is prop…
An AI model for digital breast tomosynthesis screening in BreastScreen Norway showed performance similar to radiologist double reading for cancer detection, with minimal additional benefit from incorporating prior mammograms.
Retrospective ENIGMA mega-analysis: No overall brain age difference in specific phobia vs controls, but younger adults (22-35) with formal diagnosis had +1.2 y brain age (d=0.14).
MRI-based breast texture analysis may assist in diagnosing BI-RADS category 4 lesions, potentially reducing unnecessary biopsies. (Performance metrics and study details are not reported in the source snippet.)
A foundational primer explains how radiology AI tools process images, present results, and integrate with workflows. Misalignments at the radiologist-AI interface can create cognitive burdens and diminish the efficiency gains promised by marketed solutions. Understanding the int…
In a retrospective study of 195 patients, noncontrast abbreviated MRI (NC-AMRI) showed lower sensitivity (78.3% vs 92.4%) and specificity (79.6% vs 95.1%) than full-sequence MRI for detecting intrahepatic HCC recurrence after TACE, hindering its utility as a standalone monitorin…
Retrospective: RECIBM bone metastasis criteria had high agreement with MD Anderson, PERCIST, EORTC (κ=0.80–0.98) and reclassified 19% of 84 patients. Response was associated with OS (HR 0.07) and bone progression-free survival (HR 0.03).
In a multicenter study of 492 acute myocarditis patients, left ventricular (LV) global entropy ≥8.5 on cardiac MRI independently tripled the risk of major adverse cardiovascular events (hazard ratio 3.33). Late gadolinium enhancement entropy also remained an independent predicto…
In a post hoc analysis of MAGIC-MT trial (697 patients), the presence of hyperdense capsule sign on CT identified patients who benefited from MMA embolization for nonacute SDH: recurrence 5.0% vs 12.0% (P=.009) and serious AEs 5.9% vs 15.1% (P=.002). No benefit in HDCS-negative…
