Review: Imaging prediction of hematoma expansion after ICH has progressed from CTA spot sign and NCCT markers to AI-driven radiomics and multimodal fusion, but interpretability and generalizability remain challenges.
In a retrospective 155-patient study, dual-phase CT radiomics predicted acute kidney injury after cardiac arrest with an AUC of 0.783 in the test set, but feature selection was unstable and repeated resampling median AUC was 0.663 — early and not yet externally validated.
A channel-attention high-resolution network segmented thyroid nodules on CT with a Dice coefficient of 78.6% overall, reaching 85.5% for benign nodules versus 66.2% for malignant ones, while reducing computational complexity by 73% compared to standard HRNet.
DriverNet MRI model predicted EGFR/ALK mutation status in NSCLC brain metastases with AUCs of 0.952–0.962 in external test cohorts, outperforming clinical-only models. Prospective validation is needed.
