WebDifferent perfusion patterns have the following probabilities of Alzheimer disease: normal: 19%. bilateral temporoparietal hypoperfusion: 82%. bilateral temporoparietal hypoperfusion and other defects: 77%. unilateral temporoparietal hypoperfusion: 57%. frontal hypoperfusion: 43%. WebResearch has shown that SPECT imaging can identify the abnormally low blood flow pattern of Alzheimer’s disease up to 9 years before the onset of noticeable symptoms. This capacity of SPECT imaging is particularly valuable for people with a family history of Alzheimer’s disease. Common Symptoms in Alzheimer’s Disease: Memory loss
