  "img_finding": "Image findings: hippocampal volume measures 8,072 mm³, 6.8% above the reference mean. With a Z-score of 0.66 (74.6th percentile), this represents normal volume . ",
  "text_data": "Age is 77.8 years. Gender is Male. Education: 14 years. MMSE: 24.0. MoCA: 17.0. Logical Memory: 0.0. APOEε4 alleles: 1.0. Biomarker levels: Florbetapir (AV45): 1.45 SUVR (significant elevated). ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume is within the normal range (Z-score 0.66), but cognitive scores (MMSE 24, MoCA 17) suggest impairment, and AV45 indicates amyloid pathology. The discrepancy between imaging and cognitive performance points to possible early neurodegeneration.  \nDiagnosis: MCI  \nConfidence: Medium",
