TECHNICAL PROCEDURE AND RESULTS Technetium labelled Ceretec was injected and SPECT images of the brain obtained. The injection was during mental stimulation conditions. Significantly decreased perfusion to the posterior frontal lobes, the parietal lobes, as well as the temporal lobes (left > right, medial more than lateral) was seen.
OVERALL IMPRESSION The most striking features are reduced perfusion to the temporal lobes and the posterior posterior frontal lobes. Reduced perfusion to the parietal lobes is also seen.
