  "img_finding": "Image findings: ventricular volume measures 89,903 mm³, 91.2% above the reference mean. With a Z-score of 2.65 (99.6th percentile), this represents significant enlargement; whole brain volume measures 1,132,080 mm³, 10.0% above the reference mean. With a Z-score of 1.31 (90.5th percentile), this represents mild enlargement. ",
  "text_data": "Age is 82.0 years. Gender is Male. Education: 16 years. MMSE: 29.0. MoCA: 23.0. Logical Memory: 15.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The ventricular volume is significantly enlarged (Z-score 2.65), suggesting atrophy, while whole brain volume is only mildly enlarged (Z-score 1.31). The MMSE is normal (29/30), but the MoCA (23/30) indicates mild cognitive impairment. APOE4 carrier status increases Alzheimer's risk.  \n\n**Diagnosis:** **MCI (Mild Cognitive Impairment)**  \n**Confidence:** **Medium** (MoCA suggests MCI, but MMSE is normal; imaging supports neurodegeneration but not severe enough for dementia diagnosis.)",
