  "img_finding": "Image findings: ventricular volume measures 35,281 mm³, 17.5% above the reference mean. With a Z-score of 0.42 (66.1th percentile), this represents normal volume ; whole brain volume measures 1,095,870 mm³, 3.4% below the reference mean. With a Z-score of -0.48 (31.5th percentile), this represents normal volume . ",
