With a Z-score of -0.61 (27.2th percentile), this represents normal volume ; hippocampal volume measures 6,708 mm³, 5.7% below the reference mean. With a Z-score of -0.52 (30.0th percentile), this represents normal volume ; whole brain volume measures 974,216 mm³, 0.0% below the reference mean. With a Z-score of -0.01 (49.8th percentile), this represents normal volume ; entorhinal cortex volume measures 3,706 mm³, 0.9% above the reference mean. With a Z-score of 0.06 (52.2th percentile), this represents normal volume ; fusiform gyrus volume measures 16,768 mm³, 1.4% below the reference mean. With a Z-score of -0.13 (44.8th percentile), this represents normal volume ; middle temporal gyrus volume measures 17,715 mm³, 7.6% below the reference mean.
