  "img_finding": "Image findings: ventricular volume measures 63,752 mm³, 185.4% above the reference mean. With a Z-score of 4.64 (100.0th percentile), this represents profound enlargement; whole brain volume measures 859,692 mm³, 16.5% below the reference mean. With a Z-score of -2.05 (2.0th percentile), this represents significant atrophy. ",
  "text_data": "Age is 62.2 years. Gender is Female. Education: 18 years. MMSE: 11.0. MoCA: 8.0. Logical Memory: 1.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 1.30 SUVR (moderate elevated). ",

  "gpt_diagnosis": "Reasoning: The data shows profound ventricular enlargement (Z-score 4.64) and significant whole brain atrophy (Z-score -2.05), consistent with advanced neurodegeneration. The low MMSE (11) and MoCA (8) scores indicate severe cognitive impairment, while the absence of APOE4 and moderate AV45 elevation suggest mixed pathology (likely Alzheimer's and vascular contributions).  \nDiagnosis: Dementia  \nConfidence: High",
