With a Z-score of -0.92 (17.8th percentile), this represents normal volume ; whole brain volume measures 1,159,520 mm³, 2.2% above the reference mean. With a Z-score of 0.31 (62.2th percentile), this represents normal volume ; entorhinal cortex volume measures 4,521 mm³, 6.1% above the reference mean. With a Z-score of 0.42 (66.2th percentile), this represents normal volume ; fusiform gyrus volume measures 21,047 mm³, 5.7% above the reference mean. With a Z-score of 0.48 (68.3th percentile), this represents normal volume ; middle temporal gyrus volume measures 23,735 mm³, 5.9% above the reference mean.
