With a Z-score of 0.75 (77.4th percentile), this represents normal volume ; whole brain volume measures 894,027 mm³, 13.1% below the reference mean. With a Z-score of -1.63 (5.1th percentile), this represents moderate atrophy; entorhinal cortex volume measures 2,530 mm³, 35.0% below the reference mean. With a Z-score of -2.71 (0.3th percentile), this represents significant atrophy; fusiform gyrus volume measures 14,375 mm³, 21.1% below the reference mean. With a Z-score of -2.37 (0.9th percentile), this represents significant atrophy; middle temporal gyrus volume measures 12,020 mm³, 41.4% below the reference mean. With a Z-score of -3.68 (0.0th percentile), this represents profound atrophy. ",
