Imaging myelin is important for studies related to white
matter (WM) diseases. We investigated the feasibility of
mapping WM characteristics using interslice MT asymmetry
and MT ratio using a recent method termed Alternate
Ascending/Descending Directional Navigation (ALADDIN).
The WM contrast (compared to gray matter and muscle) was
much higher in MT asymmetry images than in MT ratio
images, and the two images showed slightly different WM
information in subcortical regions, indicating that
combination of MT ratio and MT asymmetry may be a
promising tool for better understanding of WM
characteristics.
