  "img_finding": "Image findings: ventricular volume measures 72,916 mm³, 55.1% above the reference mean. With a Z-score of 1.60 (94.5th percentile), this represents moderate enlargement; hippocampal volume measures 6,320 mm³, 9.3% below the reference mean. With a Z-score of -0.80 (21.1th percentile), this represents normal volume ; whole brain volume measures 1,177,330 mm³, 14.4% above the reference mean. With a Z-score of 1.89 (97.0th percentile), this represents moderate enlargement. ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume is within normal limits (Z-score -0.80), and cognitive scores (MMSE 28, MoCA 24) are borderline normal/mildly impaired but not strongly indicative of dementia. Ventricular and whole brain volume enlargement may reflect age-related atrophy rather than neurodegenerative disease.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium",
