FIG 7. A and B, Conventional MR images (A) and Z score images (B) obtained in a 73-year-old patient with late-onset AD (MMSE score = 23). Medial temporal atrophy can be detected by visual inspection of the conventional T1-weighted images. By using the Z score map, the region and degree of atrophy can be detected easily; note that the left hippocampal atrophy is stronger than the right. L indicates left; R, right.
