Comparative Study Clinical Trial Controlled Clinical TrialMultitracer study with positron emission tomography in Creutzfeldt-Jakob disease.
During the period February 1997 to April 2000, 15 patients with clinical symptoms of Creutzfeldt-Jakob disease (CJD) were referred to Uppsala University PET Centre. Positron emission tomography (PET) was performed to detect characteristic signs of the disease, e.g. neuronal death and/or astrocytosis in the brain. The examinations were performed in one session starting with oxygen-15 labelled water scan to measure regional cerebral blood flow, followed by imaging with the monoamine oxidase B inhibitor N-[(11)C-methyl]- L-deuterodeprenyl (DED) to assess astrocytosis in the brain and finally imaging with fluor-18 2-fluorodeoxyglucose (FDG) to assess regional cerebral glucose metabolism (rCMR(glu)) [corrected]. ⋯ One of the patients had Sjögren's syndrome, one had paraneoplastic limbic encephalitis and the third recovered spontaneously. In the other three patients, the DED binding was normal despite a hypometabolic glucose pattern. In conclusion, the PET findings obtained using DED and FDG paralleled neuropathological findings indicating neuronal dysfunction and astrocytosis, changes that are found in CJD.
