  "img_finding": "Image findings: hippocampal volume measures 6,529 mm³, 15.0% below the reference mean. With a Z-score of -1.69 (4.6th percentile), this represents moderate atrophy. ",
  "text_data": "Age is 69.4 years. Gender is Female. Education: 16 years. MMSE: 29.0. MoCA: 27.0. Logical Memory: 19.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 1.09 SUVR (normal ); Amyloid beta: 1035.00 pg/mL (normal ); Total tau: 130.60 pg/mL (mild reduced); Phosphorylated tau: 10.81 pg/mL (mild reduced). ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume shows moderate atrophy (Z-score -1.69), but cognitive scores (MMSE 29, MoCA 27) are within normal range, and biomarkers (Aβ normal, AV45 normal) do not support Alzheimer's pathology. Reduced T-tau and P-tau are atypical for AD.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to hippocampal atrophy without cognitive or biomarker corroboration for MCI/dementia)",
