FDG-PET across the clinical phenotypes of AD: A typical AD, B PCA, and C lvPPA. Panel A shows symmetrical bilateral parietal and temporal hypometabolism in a patient with typical AD. Panel B shows bilateral reduction in parieto-tempo-occipital metabolism in a patient with PCA. Panel C shows greater hypometabolism in the left parieto-temporal region compared with the right parieto-temporal region in a patient with lvPPA. Panels 1 and 2 show different depths within the brain. The FDG-PET images in Fig. 3 are courtesy of Dr. Marie-Odile Habert (Department of Nuclear Medicine, Pitié-Salpêtrière Hospital, APHP, Paris). AD, Alzheimer’s disease; FDG, fluorodeoxyglucose; lvPPA, logopenic variant of primary progressive aphasia; PCA, posterior cortical atrophy; PET, positron emission tomography
