  "img_finding": "Image findings: ventricular volume measures 26,974 mm³, 3.9% below the reference mean. With a Z-score of -0.09 (46.4th percentile), this represents normal volume ; hippocampal volume measures 7,158 mm³, 0.6% above the reference mean. With a Z-score of 0.06 (52.2th percentile), this represents normal volume ; whole brain volume measures 933,452 mm³, 4.2% below the reference mean. With a Z-score of -0.53 (29.7th percentile), this represents normal volume ; entorhinal cortex volume measures 3,144 mm³, 14.4% below the reference mean. With a Z-score of -0.88 (18.8th percentile), this represents normal volume ; fusiform gyrus volume measures 14,865 mm³, 12.6% below the reference mean. With a Z-score of -1.15 (12.5th percentile), this represents mild atrophy; middle temporal gyrus volume measures 22,196 mm³, 15.8% above the reference mean. With a Z-score of 1.37 (91.5th percentile), this represents mild enlargement. ",
