  "img_finding": "Image findings: ventricular volume measures 96,063 mm³, 149.4% above the reference mean. With a Z-score of 3.58 (100.0th percentile), this represents profound enlargement; whole brain volume measures 1,061,310 mm³, 1.7% below the reference mean. With a Z-score of -0.22 (41.4th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is significantly enlarged (149.4% above mean, Z-score 3.58), indicating substantial atrophy, while whole brain volume is near normal. The MMSE score of 19 suggests cognitive impairment, and the presence of one APOE4 allele increases Alzheimer's risk.  \nDiagnosis: Dementia (likely Alzheimer's disease)  \nConfidence: High",
