  "img_finding": "Image findings: hippocampal volume measures 8,151 mm³, 14.6% above the reference mean. With a Z-score of 1.34 (90.9th percentile), this represents mild enlargement. ",
  "text_data": "Age is 72.9 years. Gender is Female. Education: 14 years. MMSE: 30.0. MoCA: 25.0. Logical Memory: 14.0. APOEε4 alleles: 1.0. ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume is mildly enlarged (14.6% above mean, Z-score 1.34), which is atypical for Alzheimer's but not diagnostic. MMSE is normal (30/30), while MoCA (25/30) suggests mild cognitive impairment (MCI). APOE4 carrier status increases Alzheimer's risk but is not definitive.  \nDiagnosis: **MCI**  \nConfidence: **Medium** (MoCA supports MCI, but hippocampal enlargement is unusual for typical Alzheimer's progression).",
