Alzheimer's disease: Perfusion SPECT -- Slice #28
Tour 2: Next/Previous/Start: Here is a mid-ventricular slice which demonstrates the commonest finding in functional imaging of Alzheimer's disease. (Check the corresponding anatomic image by choosing the MR-T2 tickmark on the timeline, or by using the arrow buttons at right) The dark blue regions in the parietal lobes represent areas of decreased blood flow or perfusion. This reduction in blood flow is due in part to the underlying atrophy, in part to the presence of diseased brain, and in part to the functional "disconnection" of this from other brain regions affected by the disease.
