  "img_finding": "Image findings: hippocampal volume measures 6,696 mm³, 11.4% below the reference mean. With a Z-score of -1.11 (13.3th percentile), this represents mild atrophy. ",
  "text_data": "Age is 76.1 years. Gender is Male. Education: 15 years. Handedness: Right. Race: White. Medical history: Cardiovascular; Musculoskeletal; Endocrine-Metabolic; Renal-Genitourinary. MMSE: 29.0. MoCA: 24.0. Logical Memory: 18.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 1.04 SUVR (normal ); Amyloid beta: 1139.00 pg/mL (normal ); Total tau: 218.10 pg/mL (normal ); Phosphorylated tau: 18.18 pg/mL (normal ). ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume shows mild atrophy (11.4% below reference mean, Z-score -1.11), but cognitive scores (MMSE 29, MoCA 24) are within normal to borderline range. Biomarkers (Aβ, tau, AV45) are normal, and there is no APOE4 risk allele.  \nDiagnosis: **CN (Cognitively Normal)**  \nConfidence: **Medium** (Mild hippocampal atrophy could suggest early changes, but normal biomarkers and strong cognitive performance support CN.)",
