Posterior Cortical Atrophy Presenting with Superior Arcuate Field Defect

Figure 5

Single-photon-emission computed tomography (SPECT). Cerebral perfusion scan 99mTc HMPAO Z-score reconstructed images. Statistical mapping carried out using the NeuroSTAT programme. Demonstrating asymmetrically decreased activity involving the parietal, occipital, and, to a lesser extent, temporal lobe cortex, greater on the right than on the left. RT.LAT = right lateral; LT.LAT = left lateral; SUP = superior; INF = inferior; ANT = anterior; POST = posterior; RT.MED = right medial; LT.MED = left medial. GLB = global; THL = thalamus; CBL = cerebellum; PNS = pons.
