  "img_finding": "Image findings: hippocampal volume measures 5,969 mm³, 14.3% below the reference mean. With a Z-score of -1.24 (10.8th percentile), this represents mild atrophy. ",
  "text_data": "Age is 85.7 years. Gender is Male. Education: 18 years. MMSE: 30.0. MoCA: 28.0. Logical Memory: 9.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 1.28 SUVR (moderate elevated). ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume shows mild atrophy (14.3% below reference mean, Z-score -1.24), but cognitive scores (MMSE 30, MoCA 28) are intact, and there is no APOE4 risk allele. Moderate AV45 (amyloid) elevation suggests some pathological burden, but cognition remains preserved.  \nDiagnosis: **CN (Cognitively Normal)**  \nConfidence: **Medium** (due to conflicting biomarkers—hippocampal atrophy and amyloid elevation—but strong cognitive performance)",
