Towards Explainability in Deep Learning for Detection of Five Major Intracranial Hemorrhage Subtypes on Head CT Using Multi-window DICOM Imaging and Patient-Level Cross-Validation.

An AI system detects brain bleeding on CT scans with 97% accuracy, though rare subtypes remain challenging and real-world validation is needed.

An explainable ResNet34 deep learning framework trained on DICOM-native three-window CT (brain/subdural/bone) achieved robust multi-label ICH detection (ROC AUC 0.97+) with patient-level cross-validation on 18,938 patients from the RSNA 2019 challenge, accompanied by multi-method attribution analysis supporting model interpretability. Performance on rare subtypes (particularly epidural hemorrhage) remains limited, and prospective external validation is required.
