MP2RAGE is 3D T1-weighted MR sequence used for high GM/WM contrast imaging, enabling morphometry, brain segmentation and T1 mapping. Despite these advantages, it suffers from long acquisition times, hindering broad clinical adoption. In this work, brain data obtained from 29 patients with various pathologies using the GRAPPAx3-accelerated reference (8:22 min) and a new compressed-sensing version (4:00 min) of the MP2RAGE were compared with respect to brain volumetry and T1 mapping results. Very high agreement was observed between the two versions. These results pave the way for a broader use of CS-MP2RAGE, eventually enabling its clinical use.
