Previous imaging studies of Alzheimer's disease have shown regional abnormalities in patients using both diffusion tensor imaging (DTI) and magnetization transfer ratio (MTR). We build upon the work of previous studies by combining two commonly used methods into one automated process. In this study, we utilize an autoregional method to isolate specific brain regions, and then perform an autotractography algorithm to target white matter tracts associated with the included brain regions. This procedure detects previously unseen MTR differences between the white matter fiber tracts of AD patients and healthy controls.
