  "img_finding": "Image findings: ventricular volume measures 34,426 mm³, 6.9% below the reference mean. With a Z-score of -0.19 (42.6th percentile), this represents normal volume ; hippocampal volume measures 6,687 mm³, 3.0% above the reference mean. With a Z-score of 0.24 (59.4th percentile), this represents normal volume ; whole brain volume measures 1,049,500 mm³, 13.1% above the reference mean. With a Z-score of 1.57 (94.2th percentile), this represents moderate enlargement; entorhinal cortex volume measures 3,815 mm³, 10.2% above the reference mean. With a Z-score of 0.55 (70.9th percentile), this represents normal volume ; fusiform gyrus volume measures 20,176 mm³, 25.2% above the reference mean. With a Z-score of 1.90 (97.1th percentile), this represents moderate enlargement; middle temporal gyrus volume measures 20,310 mm³, 12.7% above the reference mean. With a Z-score of 1.13 (87.0th percentile), this represents mild enlargement. ",
