  "img_finding": "Image findings: hippocampal volume measures 9,023 mm³, 19.4% above the reference mean. With a Z-score of 1.89 (97.1th percentile), this represents moderate enlargement. ",
  "text_data": "Age is 72.3 years. Gender is Male. Education: 12 years. MMSE: 27.0. MoCA: 22.0. Logical Memory: 18.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume is significantly above the reference mean, which is unusual for Alzheimer's disease (typically associated with atrophy). The MMSE score of 27 is within normal limits, but the MoCA score of 22 suggests mild cognitive impairment (MCI). The absence of APOE4 reduces Alzheimer's risk.  \nDiagnosis: MCI  \nConfidence: Medium (due to conflicting hippocampal volume and cognitive scores)",
