  "img_finding": "Image findings: ventricular volume measures 57,307 mm³, 55.0% above the reference mean. With a Z-score of 1.49 (93.1th percentile), this represents mild enlargement; hippocampal volume measures 6,149 mm³, 5.3% below the reference mean. With a Z-score of -0.43 (33.5th percentile), this represents normal volume ; whole brain volume measures 802,883 mm³, 13.5% below the reference mean. With a Z-score of -1.62 (5.3th percentile), this represents moderate atrophy. ",

  "gpt_diagnosis": "Reasoning: The patient shows moderate whole brain atrophy and mild ventricular enlargement, but hippocampal volume is within normal range. Cognitive scores (MMSE 26, MoCA 24) are borderline, and biomarkers (Aβ, tau, AV45) are normal, suggesting no significant Alzheimer's pathology.  \nDiagnosis: MCI  \nConfidence: Medium",
