Diffusion tensor imaging of white matter degeneration in Alzheimer's disease and mild cognitive impairment

IK Amlien, AM Fjell - Neuroscience, 2014 - Elsevier
Alzheimer’s disease (AD) has traditionally been regarded as a disease of the gray matter (GM).
However, the advent of diffusion tensor imaging (DTI) has contributed to new knowledge …
