  "img_finding": "Image findings: hippocampal volume measures 9,183 mm³, 14.4% above the reference mean. With a Z-score of 1.44 (92.5th percentile), this represents mild enlargement. ",
  "text_data": "Age is 62.3 years. Gender is Male. Education: 20 years. MMSE: 24.0. MoCA: 20.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume is mildly enlarged (14.4% above mean, Z-score 1.44), which is atypical for Alzheimer's but does not rule out cognitive impairment. The MMSE (24) and MoCA (20) scores suggest mild cognitive deficits, though APOE4-negative status reduces Alzheimer's risk.  \nDiagnosis: **MCI**  \nConfidence: **Medium** (cognitive scores indicate impairment, but hippocampal enlargement is unusual for typical AD progression)",
