  "img_finding": "Image findings: ventricular volume measures 52,182 mm³, 85.9% above the reference mean. With a Z-score of 1.97 (97.5th percentile), this represents moderate enlargement; hippocampal volume measures 7,024 mm³, 1.3% below the reference mean. With a Z-score of -0.12 (45.4th percentile), this represents normal volume ; whole brain volume measures 1,121,880 mm³, 15.1% above the reference mean. With a Z-score of 1.90 (97.1th percentile), this represents moderate enlargement. ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is moderately enlarged (85.9% above reference mean, Z-score 1.97), which can indicate atrophy, but hippocampal volume is normal (1.3% below reference mean, Z-score -0.12). Cognitive scores (MMSE 28, MoCA 27) are within normal range, and the absence of APOE4 reduces genetic risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (ventricular enlargement is notable, but cognitive performance and hippocampal volume suggest no impairment)",
