We used single photon emission computed tomography with the blood flow tracer [123I] N-
isopropyl P-iodoamphetamine (IMP) to study regional cerebral blood flow (rCBF) in 50 mildly …

Objective: To examine the ability of relative regional cerebral blood flow as measured by
single photon emission computed tomography to predict longitudinal course of cognitive …

Regional cerebral blood flow (CBF) was examined in 27 patients with Parkinson's disease
using single-photon emission computed tomography and N-isopropyl-p-[123I] …

• Objective.—To study the relationship between relative regional cerebral blood flow (rCBF)
and performance on a variety of neuropsychological tests in a group of subjects with …

• We performed this study to determine whether early-and late-onset Alzheimer's disease
differ physiologically. Ten patients with a presenile (before 65 years old) onset of the …

Thirty five patients with dementia of the Alzheimer type (DAT) and 35 controls matched for
age, sex and handedness were investigated using single photon emission computer …

The purpose of this study was to explore the influence of age on regional cerebral blood flow
(rCBF) patterns in patients with Alzheimer's disease (AD). Single photon emission computed …

Studies of Alzheimer's disease using single‐photon emission computed tomography
(SPECT) and positron emission tomography (PET) have found reductions in blood flow and …

Single photon emission tomography (SPET) with the lipophilic blood flow marker 99mTc-
hexamethyl propyleneamine oxime (99mTc-HMPAO) has been used to determine regional …

In the normal brain as well as in Alzheimer's disease (AD), regional cerebral blood flow
(CBF) is coupled to metabolic demand and, therefore, changes in CBF reflect variations in …
