To evaluate the effect of apolipoprotein E (APOE) epsilon 4 allele on regional cerebral perfusion (rCBF) changes, pulsed arterial spin labeling (ASL) imaging and isotropic volumetric T1-weighted imaging were scanned in 25 subjects with AD, 25 with amnestic mild cognitive impairment(MCI) and 25 cognitively normal(CN) subjects. All subjects were divided into carrier or noncarriers of the epsilon4 allele. In each subject group, we also evaluated the rCBF change between carrier and noncarrier groups. rCBF values were significantly reduced in the CN and AD groups, but increased in MCI in the carriers of the epsilon4 allele.
