Morphologic and functional imaging studies have not always given concordant results about
brain areas showing atrophic changes and reduced flow or metabolism in Alzheimer's …

RESULTS The inaccuracy index for AIR calculated on CBF images (based on voxel data)
was 1.8% ±0.11% and 2.3% ±0.28% for healthy subjects and AD patients, respectively …

Purpose: To determine the usefulness of brain perfusion SPECT for evaluating the severity
and progression of Alzheimer's disease (AD). Methods: Eighty-four AD patients were …

Background. Patients with objective evidence of memory impairment have been considered
to be at risk for developing Alzheimer's disease (AD). However, little is known about patterns …

The aim of this SPECT study was to determine the initial abnormality and longitudinal
changes in regional cerebral blood flow (rCBF) in early Alzheimer's disease (AD) using …

Purpose To determine the relationship of differing levels of education on regional cerebral
blood flow (rCBF) in patients with Alzheimer's disease (AD). Methods Fifty-three patients with …

The purpose of this study was to elucidate whether cerebral blood flow (CBF) can better
characterize perfusion abnormalities in predementia stages of Alzheimer's disease (AD) …

Objectives–Alzheimer's disease (AD), frontotemporal dementia (FTD) and vascular
dementia (VaD) are the three most common causes of young onset dementias. Most …

BACKGROUND AND PURPOSE: The progression of cognitive deterioration in patients with
Alzheimer's disease (AD) is considerably variable. The ability to predict the progression rate …

Objective To identify group differences in the prodromal phase of Alzheimer disease (AD)
using quantitative single-photon emission computed tomography (SPECT) perfusion and …
