  "img_finding": "Image findings: hippocampal volume measures 4,801 mm³, 36.5% below the reference mean. With a Z-score of -3.56 (0.0th percentile), this represents profound atrophy. ",
  "text_data": "Age is 75.9 years. Gender is Male. Education: 16 years. MMSE: 27.0. MoCA: 23.0. Logical Memory: 4.0. APOEε4 alleles: 2.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The hippocampal volume is severely reduced (Z-score -3.56, 0.0th percentile), indicating profound atrophy, which is strongly associated with Alzheimer's disease. Despite relatively preserved cognitive scores (MMSE 27, MoCA 23), the structural changes suggest early neurodegeneration.  \n**Diagnosis:** Mild Cognitive Impairment (MCI)  \n**Confidence:** Medium (cognitive scores are borderline, but hippocampal atrophy is severe)",
