Abstract

QSMDiff achieves high-quality and accurate QSM reconstruction from both standard GRE and rapid EPI scans for ICH assessment. By integrating a 2.5D training strategy with synthetic ICH augmentation, it delivers accurate and reliable susceptibility maps even from lower-quality acquisitions, offering a practical solution for fast and robust ICH assessment.
