The purpose of this study is to implement a distortion-free technique, termed DIADEM (Distortion-free Imaging: A Double Encoding Method) into brain MR Elastography (MRE). The distortion-free whole-brain MRE images with 2-mm isotropic resolution can be achieved using the proposed technique within 6 minutes. The feasibility of DIADEM-MRE was successfully demonstrated on healthy volunteers and patients with brain tumors.
