  "img_finding": "Image findings: hippocampal volume measures 6,006 mm³, 21.8% below the reference mean. With a Z-score of -2.45 (0.7th percentile), this represents significant atrophy. ",
  "text_data": "Age is 69.2 years. Gender is Female. Education: 12 years. MMSE: 26.0. MoCA: 25.0. Logical Memory: 5.0. APOEε4 alleles: 1.0. ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume is significantly reduced (Z-score -2.45, 0.7th percentile), which is strongly associated with Alzheimer's pathology. Cognitive scores (MMSE 26, MoCA 25) are borderline but still within normal range, suggesting possible early cognitive changes.  \nDiagnosis: **MCI (Mild Cognitive Impairment)**  \nConfidence: **Medium** (Cognitive scores are not yet impaired enough for dementia, but hippocampal atrophy is concerning for early neurodegeneration.)",
