  "img_finding": "Image findings: ventricular volume measures 17,675 mm³, 52.2% below the reference mean. With a Z-score of -1.41 (7.9th percentile), this represents mild atrophy; whole brain volume measures 891,449 mm³, 4.0% below the reference mean. With a Z-score of -0.47 (31.7th percentile), this represents normal volume . ",
