  "img_finding": "Image findings: ventricular volume measures 33,949 mm³, 8.2% below the reference mean. With a Z-score of -0.22 (41.3th percentile), this represents normal volume ; hippocampal volume measures 6,259 mm³, 3.6% below the reference mean. With a Z-score of -0.29 (38.5th percentile), this represents normal volume ; whole brain volume measures 892,346 mm³, 3.9% below the reference mean. With a Z-score of -0.46 (32.2th percentile), this represents normal volume ; entorhinal cortex volume measures 3,342 mm³, 3.5% below the reference mean. With a Z-score of -0.19 (42.5th percentile), this represents normal volume ; fusiform gyrus volume measures 14,418 mm³, 10.5% below the reference mean. With a Z-score of -0.79 (21.5th percentile), this represents normal volume ; middle temporal gyrus volume measures 16,157 mm³, 10.4% below the reference mean. With a Z-score of -0.92 (17.8th percentile), this represents normal volume . ",
