With a Z-score of -0.98 (16.4th percentile), this represents normal volume ; hippocampal volume measures 6,808 mm³, 2.3% below the reference mean. With a Z-score of -0.20 (42.1th percentile), this represents normal volume ; whole brain volume measures 1,035,960 mm³, 0.7% above the reference mean. With a Z-score of 0.09 (53.4th percentile), this represents normal volume ; entorhinal cortex volume measures 3,949 mm³, 0.5% below the reference mean. With a Z-score of -0.03 (48.7th percentile), this represents normal volume ; fusiform gyrus volume measures 16,682 mm³, 7.7% below the reference mean. With a Z-score of -0.66 (25.4th percentile), this represents normal volume ; middle temporal gyrus volume measures 18,470 mm³, 8.4% below the reference mean.
