With a Z-score of 0.20 (58.0th percentile), this represents normal volume ; hippocampal volume measures 7,699 mm³, 8.2% above the reference mean. With a Z-score of 0.75 (77.4th percentile), this represents normal volume ; whole brain volume measures 921,446 mm³, 5.5% below the reference mean. With a Z-score of -0.69 (24.6th percentile), this represents normal volume ; entorhinal cortex volume measures 3,319 mm³, 9.6% below the reference mean. With a Z-score of -0.59 (27.7th percentile), this represents normal volume ; fusiform gyrus volume measures 15,263 mm³, 10.3% below the reference mean. With a Z-score of -0.94 (17.5th percentile), this represents normal volume ; middle temporal gyrus volume measures 18,396 mm³, 4.0% below the reference mean.
