  "img_finding": "Image findings: ventricular volume measures 16,030 mm³, 28.2% below the reference mean. With a Z-score of -0.71 (24.0th percentile), this represents normal volume ; hippocampal volume measures 7,128 mm³, 7.2% below the reference mean. With a Z-score of -0.81 (20.8th percentile), this represents normal volume ; whole brain volume measures 1,034,000 mm³, 0.5% above the reference mean. With a Z-score of 0.06 (52.3th percentile), this represents normal volume ; entorhinal cortex volume measures 3,926 mm³, 0.8% above the reference mean. With a Z-score of 0.07 (52.6th percentile), this represents normal volume ; fusiform gyrus volume measures 17,915 mm³, 1.6% below the reference mean. With a Z-score of -0.18 (42.8th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,363 mm³, 4.1% above the reference mean. With a Z-score of 0.37 (64.3th percentile), this represents normal volume . ",
