(99m)Tc-HMPAO SPECT and (18)F-FDG PET/CT scans showed cerebral hypoperfusion and hypometabolism in patients with cognitive impairment, even in patients with clinical diagnosis of SMC. In patients with a normal cerebral blood flow SPECT, brain glucose cerebral hypometabolism can be detected. In some patients, the extension of FDG hypometabolism is more pronounced than that corresponding to the hypoperfusion area.
