  "img_finding": "Image findings: ventricular volume measures 32,637 mm³, 15.3% below the reference mean. With a Z-score of -0.37 (35.7th percentile), this represents normal volume ; hippocampal volume measures 7,676 mm³, 1.5% above the reference mean. With a Z-score of 0.15 (56.0th percentile), this represents normal volume ; whole brain volume measures 1,124,150 mm³, 4.1% above the reference mean. With a Z-score of 0.54 (70.5th percentile), this represents normal volume ; entorhinal cortex volume measures 3,578 mm³, 12.7% below the reference mean. With a Z-score of -0.86 (19.4th percentile), this represents normal volume ; fusiform gyrus volume measures 18,651 mm³, 1.0% below the reference mean. With a Z-score of -0.08 (46.6th percentile), this represents normal volume ; middle temporal gyrus volume measures 19,109 mm³, 10.5% below the reference mean. With a Z-score of -0.94 (17.4th percentile), this represents normal volume . ",
