This is a 51-year-old female with poor memory, visual tracking, dementia, and myoclonic jerking. No prior studies are
available for comparison.
Under conditions of ambient light and sound in the Division of Nuclear Medicine, the patient received an intravenous
injection of 9.24 mCi of F-18 FDG and 45 minutes later, PET imaging of the brain was carried out. Images were
reconstructed in the transverse, coronal, sagittal, and volume displays.
There is diminished F-18 FDG uptake in the parietal lobes bilaterally as well as the medial temporal and anterior temporal
regions bilaterally. There is normal FDG uptake in the frontal and occipital lobes bilaterally. There is also normal FDG
uptake along the basal ganglia and thalami.
DIMINISHED FDG UPTAKE IN THE PARIETAL LOBES AS WELL AS THE ANTERIOR TEMPORAL AND MEDIAL
TEMPORAL REGIONS WHICH ARE COMPATIBLE WITH ALZHEIMER'S DISEASE.
The patients MRI scan showed two small punctate foci of increased signal in the right centrum semiovale/corona
radiata, which may represent some very early changes of small vessel disease. Otherwise normal MRI of the head.
