  "img_finding": "Image findings: hippocampal volume measures 6,209 mm³, 10.9% below the reference mean. With a Z-score of -0.94 (17.3th percentile), this represents normal volume . ",
  "text_data": "Age is 85.8 years. Gender is Male. Education: 19 years. MMSE: 30.0. MoCA: 24.0. Logical Memory: 13.0. Laboratory findings: Hemoglobin: 16.50 (significant elevated). APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume is slightly below the reference mean but still within the normal range (Z-score -0.94). Cognitive testing shows a perfect MMSE score (30/30) but a mildly reduced MoCA (24/30), which could suggest subtle cognitive changes, though not severe enough for dementia. The absence of APOE4 reduces genetic risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to the discrepancy between MMSE and MoCA, but overall findings lean toward normal aging)",
