With a Z-score of 1.54 (93.8th percentile), this represents moderate enlargement; hippocampal volume measures 6,252 mm³, 17.3% below the reference mean. With a Z-score of -1.69 (4.6th percentile), this represents moderate atrophy; whole brain volume measures 1,114,280 mm³, 3.2% above the reference mean. With a Z-score of 0.42 (66.3th percentile), this represents normal volume ; entorhinal cortex volume measures 3,435 mm³, 16.2% below the reference mean. With a Z-score of -1.10 (13.6th percentile), this represents mild atrophy; fusiform gyrus volume measures 18,151 mm³, 3.6% below the reference mean. With a Z-score of -0.31 (37.8th percentile), this represents normal volume ; middle temporal gyrus volume measures 23,082 mm³, 8.2% above the reference mean. With a Z-score of 0.73 (76.9th percentile), this represents normal volume . ",
