With a Z-score of 0.27 (60.6th percentile), this represents normal volume ; hippocampal volume measures 7,427 mm³, 1.7% below the reference mean. With a Z-score of -0.17 (43.2th percentile), this represents normal volume ; whole brain volume measures 1,118,800 mm³, 3.7% above the reference mean. With a Z-score of 0.47 (68.2th percentile), this represents normal volume . ",
