Fig. 4

A 76-year-old woman with history of memory loss. Fluorodeoxyglucose PET/MRI (a) demonstrates hypometabolism of the parietal lobes (arrows), precuneus, and PCC as well as the visual association centers in the lateral occipital lobes (arrows in b). Metabolic activity is preserved in the medial occipital lobes (“occipital tunnel sign,” white oval in b). Pattern of hypometabolism is most suggestive of posterior cortical atrophy
