  "img_finding": "Image findings: hippocampal volume measures 11,068 mm³, 46.4% above the reference mean. With a Z-score of 4.53 (100.0th percentile), this represents profound enlargement. ",
  "text_data": "Age is 70.0 years. Gender is Male. Education: 16 years. MMSE: 29.0. MoCA: 30.0. Logical Memory: 17.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 0.95 SUVR (mild reduced); Total tau: 267.80 pg/mL (normal ); Phosphorylated tau: 25.52 pg/mL (normal ). ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume is significantly enlarged (46.4% above mean, Z-score 4.53), which is atypical for Alzheimer's pathology. Cognitive scores (MMSE 29, MoCA 30) are intact, and biomarkers (normal tau, mild reduced AV45) do not strongly support AD.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (unusual hippocampal enlargement warrants caution, but cognitive and biomarker profiles align with normal aging)",
