  "img_finding": "Image findings: hippocampal volume measures 4,654 mm³, 28.3% below the reference mean. With a Z-score of -2.27 (1.2th percentile), this represents significant atrophy. ",
  "text_data": "Age is 81.2 years. Gender is Female. Education: 14 years. MMSE: 26.0. MoCA: 19.0. Logical Memory: 7.0. APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume shows significant atrophy (Z-score -2.27, 1.2th percentile), which is strongly associated with Alzheimer's pathology. The MMSE (26) is borderline, but the MoCA (19) indicates cognitive impairment, consistent with hippocampal atrophy.  \nDiagnosis: **MCI** (likely amnestic subtype given hippocampal atrophy, but not severe enough for dementia based on MMSE).  \nConfidence: **Medium** (clinical correlation needed to rule out other causes of hippocampal atrophy).",
