RADIOPHARMACEUTICAL: 99mTc CERETEC 740 MBq
RESULTS : Tracer uptake in the left cerebral cortex is notably decreased compared with the right. This is most severe in the left temporal lobe, extending into the parietal and posterior frontal cortex. The area of perfusion reduction corresponds with the areas of cortical atrophy evident on MRI. Right cerebral cortical perfusion is normal. The basal ganglia retain normal perfusion. The left thalamus appears to be laterally displaced due to the ex vacuo dilatation of the left lateral ventricle, as is seen also on the MRI.
OVERALL IMPRESSION: Left cortical perfusion reduction involving the temporal, parietal and posterior frontal cortices, and corresponding to cortical atrophy on the MRI.
