  "img_finding": "Image findings: ventricular volume measures 16,368 mm³, 41.7% below the reference mean. With a Z-score of -0.95 (17.0th percentile), this represents normal volume ; hippocampal volume measures 7,219 mm³, 1.5% above the reference mean. With a Z-score of 0.13 (55.4th percentile), this represents normal volume ; whole brain volume measures 970,835 mm³, 0.4% below the reference mean. With a Z-score of -0.05 (48.0th percentile), this represents normal volume ; entorhinal cortex volume measures 3,574 mm³, 2.7% below the reference mean. With a Z-score of -0.17 (43.4th percentile), this represents normal volume ; fusiform gyrus volume measures 18,118 mm³, 6.5% above the reference mean. With a Z-score of 0.59 (72.3th percentile), this represents normal volume ; middle temporal gyrus volume measures 16,741 mm³, 12.7% below the reference mean. With a Z-score of -1.10 (13.6th percentile), this represents mild atrophy. ",
