Optimized reconstruction (Qr40 EID-CT vs Bv36 PCD-CT) yielded inter-scanner SD of 0.12 (patient-based). At 80% power, detecting a 10% change in total plaque volume requires 23 patients per group; 5% change needs 92 patients.
In acute ICH, clot volume on QSM correlated with edema (T3 r=0.80, p<0.001), independent of hematoma size (partial r=0.554, p=0.021). Coagulation may increase edema, relevant for procoagulant therapy.
Trained on over 0.87 million image-report pairs and externally validated across four large datasets from the US, Europe, and Asia, CLEAR achieves state-of-the-art classification performance and provides auditable zero-shot pathology detection by decomposing predictions into clin…
Real-time 3D panoramic photoacoustic angiography achieved 99.67% accuracy during freehand scanning, expanding imaging volume 42.3-fold to 50.84 mm³ in 16.7 seconds for surgical guidance.
Machine learning and multimodal imaging: Toward a more reproducible characterization of lacrimal gland lesions.
Multimodal model using plasma p-tau217, Aβ42/Aβ40, APOE4, MMSE, and hippocampal/amygdalar MRI volumes predicted amyloid-β positivity with AUC 0.875 (internal) / 0.883 (external) in mild cognitive impairment, outperforming single-modality models. Predicted risk stratified progres…
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.

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.
~50% of solitary plasmacytomas progress to symptomatic myeloma within 5 years. Updated International Myeloma Working Group recommendations emphasize advanced imaging to rule out systemic disease; local radiotherapy remains mainstay therapy.
