With a Z-score of -0.44 (33.0th percentile), this represents normal volume ; hippocampal volume measures 7,961 mm³, 5.3% above the reference mean. With a Z-score of 0.52 (69.8th percentile), this represents normal volume ; whole brain volume measures 955,656 mm³, 11.5% below the reference mean. With a Z-score of -1.49 (6.8th percentile), this represents mild atrophy; entorhinal cortex volume measures 3,763 mm³, 8.2% below the reference mean. With a Z-score of -0.56 (28.8th percentile), this represents normal volume ; fusiform gyrus volume measures 14,368 mm³, 23.7% below the reference mean. With a Z-score of -2.02 (2.2th percentile), this represents significant atrophy; middle temporal gyrus volume measures 20,295 mm³, 4.9% below the reference mean. With a Z-score of -0.44 (33.0th percentile), this represents normal volume . ",
