  "img_finding": "Image findings: ventricular volume measures 27,528 mm³, 23.2% above the reference mean. With a Z-score of 0.58 (72.0th percentile), this represents normal volume ; hippocampal volume measures 7,981 mm³, 3.9% above the reference mean. With a Z-score of 0.43 (66.8th percentile), this represents normal volume ; whole brain volume measures 1,116,560 mm³, 8.5% above the reference mean. With a Z-score of 1.06 (85.5th percentile), this represents mild enlargement; entorhinal cortex volume measures 4,713 mm³, 21.1% above the reference mean. With a Z-score of 1.63 (94.9th percentile), this represents moderate enlargement; fusiform gyrus volume measures 19,922 mm³, 9.4% above the reference mean. With a Z-score of 1.06 (85.5th percentile), this represents mild enlargement; middle temporal gyrus volume measures 23,868 mm³, 16.3% above the reference mean. With a Z-score of 1.45 (92.7th percentile), this represents mild enlargement. ",
