Methods 17 AD patients and 17 healthy man underwent rest state FMRI scans and DTI scans using Siemens Trio 3.0T MR scanner. ALFF maps and FA maps were obtained, first the ALFF maps of two groups were compared, then we take the result as the mask used for the comparison of the FA maps. Results The zones that the FA values of are abnormal is the same as the zones that ALFF are abnormal,at the same time,the FA values of AD are lower.
