Fig. 6. —Potential role of cerebral blood volume images for aiding in
diagnosis of Alzheimer's disease. Cerebral blood volume map obtained using
T2*-weighted perfusion imaging is shown in 83-year-old woman with probable
Alzheimer's disease and Mini-Mental State Examination score of 11 (normal,
27.6). Cerebral blood volume in temporoparietal regions (outlined in
white) measured approximately 65% of reference cerebral blood volume in
cerebellum in this patient (compared with mean of 112% in healthy control
subjects), indicating diminished cerebral blood volume in same regions that
are generally seen in Alzheimer's disease patients studied with positron
emission tomography and SPECT. (Reprinted with permission from
