We report on our initial experience of imaging stroke patients using a technique that achieves quantification of fat fraction (FF), QSM, and R2* simultaneously from a single multi-echo GRE (mGRE) acquisition. We collected 3T data from three stroke patients with a ~ 30-minute whole head multi-sequence protocol. By performing the joint analysis of TOF MRA, DWI, FLAIR and mGRE, we evaluated the capability of using the mGRE-based maps and images to characterize thrombus, differentiate intracranial calcifications from hemorrhages and detect white-matter lesions. Our initial results have shown the feasibility of using the mGRE technique to image stroke patients.
