With a Z-score of -0.21 (41.5th percentile), this represents normal volume ; hippocampal volume measures 8,465 mm³, 5.5% above the reference mean. With a Z-score of 0.55 (70.7th percentile), this represents normal volume ; whole brain volume measures 1,088,850 mm³, 4.0% below the reference mean. With a Z-score of -0.57 (28.4th percentile), this represents normal volume ; entorhinal cortex volume measures 4,307 mm³, 1.0% above the reference mean. With a Z-score of 0.07 (52.9th percentile), this represents normal volume ; fusiform gyrus volume measures 16,328 mm³, 18.0% below the reference mean. With a Z-score of -1.50 (6.7th percentile), this represents mild atrophy; middle temporal gyrus volume measures 23,416 mm³, 4.5% above the reference mean.
