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.
