  "img_finding": "Image findings: ventricular volume measures 28,622 mm³, 25.7% below the reference mean. With a Z-score of -0.62 (26.9th percentile), this represents normal volume ; hippocampal volume measures 7,447 mm³, 1.5% below the reference mean. With a Z-score of -0.14 (44.2th percentile), this represents normal volume ; whole brain volume measures 1,126,530 mm³, 4.4% above the reference mean. With a Z-score of 0.57 (71.5th percentile), this represents normal volume ; entorhinal cortex volume measures 3,801 mm³, 7.3% below the reference mean. With a Z-score of -0.50 (31.0th percentile), this represents normal volume ; fusiform gyrus volume measures 18,290 mm³, 2.9% below the reference mean. With a Z-score of -0.25 (40.2th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,072 mm³, 1.3% below the reference mean.
