In head and neck squamous cell carcinoma, combined sarcopenia and inflammation was associated with a 14.6-fold higher risk of death (HR 14.56, p<0.001) in a meta-analysis of 26 studies (22,408 patients). Sarcopenia alone doubled mortality risk.
Lung MRI with AI-compressed sensing in single breath-hold achieved 98.1% sensitivity (95% CI 90.2-99.7) for solid nodules ≥4 mm vs PCD-CT, with excellent size agreement (CCC 0.985). Missed calcified nodules <4 mm. Prospective single-center study.
CNN denoising increased plaque CNR (in vivo: 0.99-2.07 to 1.37-2.92, p<0.001) and improved image quality in ultrahigh-resolution photon-counting coronary CTA without affecting sharpness or stenosis.
Review finds operational electricity use, especially idle imaging equipment, is a major radiology greenhouse gas source; power management and reducing low-value imaging can cut emissions without harming care. Japan's high scanner density with low use may increase wasteful energy.
Review finds non-contrast MRI sequences suffice for surveillance of many extra-axial brain tumors (meningiomas, schwannomas, macroadenomas), reducing environmental and patient safety risks of gadolinium. For intra-axial tumors, a 'non-contrast-first' strategy may be viable in in…
An AI framework combining self-training and multimodal data designed Aβ42-targeted fluorescent probes. The model identified a candidate (TA3) with favorable binding affinity and high-contrast imaging performance, validated across multiple scaffold classes (exact performance metr…
Immediate access to cancer results via portals can expose patients to alarming terms without context. This commentary calls for 'digital result literacy'—plain-language summaries, anticipatory guidance, and training for clinicians to handle pre-informed patients.
A federated-learning-capable geometric-attention network segmented lung nodules (Dice 0.927) and classified malignancy (AUC 0.951) on three public datasets, and ran on IoT edge hardware.
Cyst shrinkage in IPMN paradoxically associated with 4.46-fold higher concomitant PDAC risk (95% CI 1.62-12.30) in a retrospective cohort. No PDAC in growth group; competing IPMN-derived carcinoma. Findings challenge benign interpretation.
In de novo metastatic soft tissue sarcoma, primary tumor surgery only improved overall survival when Ki67 ≤35% (HR 0.24, 95% CI 0.06-0.89) or total lesion glycolysis on PET/CT was low (HR 0.21, 0.04-0.97). No benefit in high Ki67 or high TLG. Retrospective, 40 patients.
Combined MRI radiomics-clinical model AUC 0.867 for prostate cancer in men with PSA 4–10 ng/mL and PI-RADS 3, vs radiomics-only AUC 0.833, clinical-only AUC 0.767. Retrospective 93 patients.
After proton RT for pediatric craniopharyngioma, brain age lagged behind chronological age by a median of 2.78 years at 5 years (βTime -0.25, 95% CI -0.41 to -0.09, p<0.001). More pronounced in younger patients and males. Retrospective, DWI model.
Y-configuration stent-assisted coiling using the low-profile LVIS Blue device was technically successful in treating wide-necked renal artery aneurysms, with no major procedural complications reported in this early series (exact figures not reported in source).
A single case report describes successful ultrasound-guided radiofrequency ablation of a recurrent post-surgical neuroma in the neck.
A case in JVIR reports a paradoxical cerebral embolism from an unrecognized portopulmonary venous shunt after gastroesophageal variceal embolization, emphasizing pre-procedural detection of such shunts to avoid this complication.
CT-based topological data analysis classifier (ra-CAPR) independently predicted overall survival (HR 1.42, P=0.005) and adjuvant chemotherapy benefit in pancreatic ductal adenocarcinoma, outperforming conventional radiomics (AUC 0.77 vs 0.72).
AI-derived prostate volume for PSA density (PSAD) calculation is non-inferior to the manual ellipsoid formula for detecting clinically significant prostate cancer (csPCa). AI-PSAD achieved an AUC of 0.79, while manual-PSAD ranged from 0.76 to 0.78 (one reader’s AUC was significa…
