  "img_finding": "Image findings: hippocampal volume measures 8,908 mm³, 15.9% above the reference mean. With a Z-score of 1.79 (96.3th percentile), this represents moderate enlargement. ",
  "text_data": "Age is 64.3 years. Gender is Female. Education: 16 years. MMSE: 30.0. MoCA: 26.0. Logical Memory: 5.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 1.00 SUVR (normal ); Total tau: 172.50 pg/mL (normal ); Phosphorylated tau: 13.97 pg/mL (mild reduced). ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume is moderately enlarged (15.9% above mean, Z-score 1.79), which is atypical for Alzheimer's. Cognitive scores (MMSE 30, MoCA 26) are within normal range, and biomarkers (normal AV45, reduced P-tau) do not strongly suggest AD pathology.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (hippocampal enlargement is unusual but not necessarily pathological; biomarkers and cognitive scores support normal cognition)",
