The signal characteristics of a novel myelin water
imaging method, direct visualization of short transverse
relaxation time component (ViSTa), have been explored.
The results show that the phase evolution and
magnetization transfer effects of ViSTa match well with
those of myelin water and are substantially different
from those of GRE. These results, in addition to short
T2* characteristics of ViSTa, further support the origin
of ViSTa signal to myelin water.
