Table 1. Changes in MR Scan Parameters.

Parameter	Standard Protocol	Parameter Changes
Voxel size (mm × mm)	2.0	1.5/2.0/2.2/2.5
SENSE factor	2	2/2.5/2.8/4
TE (msec)	80	60/70/80/90/100
NSA	2	1/2/4
b-value	800	600/800/1000/1200/1600/2000
NDGD	15	6/15/32

Note.- NDGD = number of diffusion gradient directions, NSA = number of signals acquired, SENSE = sensitivity encoding, TE = echo time
