  "img_finding": "Image findings: ventricular volume measures 47,789 mm³, 70.3% above the reference mean. With a Z-score of 1.61 (94.6th percentile), this represents moderate enlargement; hippocampal volume measures 8,209 mm³, 15.4% above the reference mean. With a Z-score of 1.41 (92.1th percentile), this represents mild enlargement; whole brain volume measures 1,011,580 mm³, 3.8% above the reference mean. With a Z-score of 0.48 (68.3th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is moderately enlarged (Z-score 1.61), which can indicate atrophy, but hippocampal volume is mildly enlarged (Z-score 1.41), which is atypical for Alzheimer's. Whole brain volume is normal. Cognitive scores (MMSE 27, MoCA 23) suggest mild cognitive impairment, but the absence of APOE4 reduces Alzheimer's risk.  \nDiagnosis: MCI  \nConfidence: Medium",
