  "img_finding": "Image findings: hippocampal volume measures 7,174 mm³, 5.1% below the reference mean. With a Z-score of -0.50 (31.0th percentile), this represents normal volume . ",
  "text_data": "Age is 73.4 years. Gender is Male. Education: 16 years. MMSE: 27.0. MoCA: 22.0. Logical Memory: 4.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 0.99 SUVR (normal ); Amyloid beta: 982.10 pg/mL (normal ); Total tau: 135.90 pg/mL (mild reduced); Phosphorylated tau: 11.87 pg/mL (mild reduced). ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume is slightly below the reference mean but still within the normal range (Z-score -0.50). Cognitive scores (MMSE 27, MoCA 22) are borderline for MCI, but biomarkers (Aβ normal, AV45 normal, reduced tau) do not strongly support neurodegeneration.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (MoCA is borderline, but biomarkers and imaging are reassuring)",
