  "img_finding": "Image findings: hippocampal volume measures 9,314 mm³, 16.0% above the reference mean. With a Z-score of 1.60 (94.5th percentile), this represents moderate enlargement. ",
  "text_data": "Age is 62.6 years. Gender is Male. Education: 20 years. MMSE: 29.0. MoCA: 22.0. Logical Memory: 10.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume is moderately enlarged (16% above mean, Z-score 1.60), which is atypical for Alzheimer's but not diagnostic. The MMSE (29/30) is normal, but the MoCA (22/30) suggests mild cognitive impairment (MCI). APOE4 carrier status increases Alzheimer's risk but is not definitive.  \n\nDiagnosis: **MCI**  \nConfidence: **Medium** (MoCA supports MCI, but hippocampal enlargement is unusual for typical Alzheimer's progression; further clinical correlation needed).",
