  "img_finding": "Image findings: hippocampal volume measures 5,820 mm³, 10.4% below the reference mean. With a Z-score of -0.83 (20.2th percentile), this represents normal volume . ",
  "text_data": "Age is 86.5 years. Gender is Female. Education: 12 years. MMSE: 26.0. MoCA: 24.0. Logical Memory: 2.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 1.56 SUVR (profound elevated); Amyloid beta: 629.80 pg/mL (mild reduced); Total tau: 241.30 pg/mL (normal ); Phosphorylated tau: 22.83 pg/mL (normal ). ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume is slightly below the reference mean but still within the normal range (Z-score -0.83). Cognitive scores (MMSE 26, MoCA 24) are borderline but not definitively impaired for age. Biomarkers show elevated AV45 (amyloid) but normal tau, suggesting amyloid pathology without significant neurodegeneration.  \nDiagnosis: **MCI** (mild cognitive impairment, likely amyloid-related)  \nConfidence: **Medium** (cognitive scores are borderline, and amyloid elevation supports early pathology, but tau is normal and hippocampal volume is not significantly reduced).",
