1 H Magnetic resonance spectroscopic imaging (MRSI) and positron emission tomography (PET) of (18) F-2-fluoro-2-deoxy-D-glucose (FDG) were performed in 18 patients with probable Alzheimer's disease (AD) and 3 normal controls. We measured the distribution and relative signal intensities of N-acetyl aspartate (NAA; a presumed neuronal marker), choline residues (Cho) representing cellular membrane compounds and of creatine-containing metabolites (Cr), and correlated these to regional cerebral glucose metabolism (rCMRGI) after coregistration of both imaging-techniques. The pattern of choline was significantly different between AD and normals (p < 0.01). RCMRGI was significantly related to Cho/Cr (r=-0.21, p<.05) and NAA/Cho quotients (r=0.35, p<.001). Our results suggest that in AD reduced neuronal energy performance and membrane abnormalities contribute to metabolic deterioration.

D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon
