For a MSA-P group and a control group, VBM, VBM regression with disease duration, and voxel-based analysis of DTI were performed, to compare the differences between the three methods in revealing the brain changes of the MSA patients.Finally,the results showed that DTI is more sensitive to brain changes in MSA-P, and could reveal larger area of abnormality. Also, DTI changes matched well with GM and WM lost revealed by VBM and VBM regression with duration,which meant that DTI could predict early brain changes in MSA-P.
