Identification and characterization of intracranial hemorrhages (ICH) are critical for appropriate management of hemorrhagic stroke patients. Hematomas at different stages have different appearance on T1 weighted, T2 weighted, and gradient echo images, partly because magnetic susceptibility varies over the time course. In this study, we applied quantitative susceptibility mapping (QSM) in vivo to directly investigate the magnetic susceptibility of hematomas at various stages.
