In this study, the whole brain MWF map from conventional MWI (GRASE) was compared to that from a novel MWI method, Direct Visualization of Short Transverse Relaxation Time Component (ViSTa). The voxel-wise correlation shows a high correlation between the two maps. Compared to the conventional MWI, ViSTa provides superior image quality with better reproducibility. It also covers a larger volume in a shorter scan time.
