With a Z-score of -0.53 (29.7th percentile), this represents normal volume ; hippocampal volume measures 7,836 mm³, 0.4% above the reference mean. With a Z-score of 0.05 (52.0th percentile), this represents normal volume ; whole brain volume measures 1,076,220 mm³, 3.4% above the reference mean. With a Z-score of 0.41 (66.0th percentile), this represents normal volume ; entorhinal cortex volume measures 4,112 mm³, 11.3% above the reference mean. With a Z-score of 0.88 (81.1th percentile), this represents normal volume ; fusiform gyrus volume measures 20,469 mm³, 11.1% above the reference mean. With a Z-score of 1.00 (84.2th percentile), this represents mild enlargement; middle temporal gyrus volume measures 21,619 mm³, 5.3% above the reference mean. With a Z-score of 0.44 (66.9th percentile), this represents normal volume . ",
