  "img_finding": "Image findings: ventricular volume measures 25,060 mm³, 16.5% below the reference mean. With a Z-score of -0.39 (34.7th percentile), this represents normal volume ; hippocampal volume measures 7,896 mm³, 1.6% below the reference mean. With a Z-score of -0.16 (43.5th percentile), this represents normal volume ; whole brain volume measures 1,148,140 mm³, 1.2% above the reference mean. With a Z-score of 0.17 (56.7th percentile), this represents normal volume ; entorhinal cortex volume measures 5,011 mm³, 17.5% above the reference mean. With a Z-score of 1.21 (88.8th percentile), this represents mild enlargement; fusiform gyrus volume measures 21,407 mm³, 7.5% above the reference mean. With a Z-score of 0.63 (73.4th percentile), this represents normal volume ; middle temporal gyrus volume measures 22,523 mm³, 0.5% above the reference mean. With a Z-score of 0.04 (51.6th percentile), this represents normal volume . ",
