With a Z-score of -0.21 (41.7th percentile), this represents normal volume ; hippocampal volume measures 7,523 mm³, 2.1% below the reference mean. With a Z-score of -0.24 (40.7th percentile), this represents normal volume ; whole brain volume measures 971,870 mm³, 5.6% below the reference mean. With a Z-score of -0.69 (24.4th percentile), this represents normal volume ; entorhinal cortex volume measures 4,512 mm³, 15.9% above the reference mean. With a Z-score of 1.23 (89.1th percentile), this represents mild enlargement; fusiform gyrus volume measures 19,841 mm³, 9.0% above the reference mean. With a Z-score of 1.01 (84.3th percentile), this represents mild enlargement; middle temporal gyrus volume measures 19,228 mm³, 6.3% below the reference mean.
