  "img_finding": "Image findings: hippocampal volume measures 7,317 mm³, 3.2% below the reference mean. With a Z-score of -0.31 (37.7th percentile), this represents normal volume . ",
  "text_data": "Age is 74.1 years. Gender is Male. Education: 18 years. MMSE: 26.0. MoCA: 17.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume is within normal range (Z-score -0.31), but cognitive testing shows significant impairment (MoCA 17/30, below typical MCI cutoff of 26). The MMSE of 26 is borderline, but the MoCA suggests notable cognitive deficits.  \nDiagnosis: MCI  \nConfidence: Medium (discrepancy between MMSE and MoCA warrants caution, but MoCA is more sensitive for early impairment)",
