We studied a 62-year-old man with Creutzfeldt-Jakob disease(CJD),using positron emission tomography(PET)and(18Fl)-2-fluoro2-deoxy-D-glucose(FDG). Glucose metabolism was heterogeneously decreased throughout the brain.At autopsy,regional distributions of spongiosis,astrogliosis,and neuronal loss correlated with premortem regional metabolic deficits.These results suggest that PET with FDG may provide metabolic regional markers for CJD neuropathology. |
