| Research Abstract |
To clarify the histopathological background of neuromelanin imaging (NMI), we performed NMI-pathologic correlations of autopsied btrains. We also evaluated cerebral blood flow using single photon emission CT with 99mTc-ECD in patients undertaken NMI. NMI well reflected amount of neuromelanin-containing neurons of the substantia nigra of the midbrain. Patients with decreased signal intensity in NMI showed significantly lower regional cerebral blood flow in the precuneus, cuneus, and posterior part of the cingulate gyrus.
