  "img_finding": "Image findings: hippocampal volume measures 3,800 mm³, 46.6% below the reference mean. With a Z-score of -4.27 (0.0th percentile), this represents profound atrophy. ",
  "text_data": "Age is 75.0 years. Gender is Female. Education: 16 years. MMSE: 9.0. MoCA: 0.0. Logical Memory: 0.0. APOEε4 alleles: 1.0. Biomarker levels: Florbetapir (AV45): 1.88 SUVR (profound elevated). ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume is severely reduced (46.6% below mean, Z-score -4.27), indicating profound atrophy. Combined with very low MMSE (9) and MoCA (0) scores, elevated AV45 (amyloid burden), and APOE4 positivity, this strongly suggests advanced neurodegeneration.  \nDiagnosis: **Dementia** (likely Alzheimer’s disease)  \nConfidence: **High**",
