  "img_finding": "Image findings: hippocampal volume measures 4,663 mm³, 34.5% below the reference mean. With a Z-score of -3.16 (0.1th percentile), this represents profound atrophy. ",
  "text_data": "Age is 78.3 years. Gender is Female. Education: 15 years. MMSE: 23.0. MoCA: 15.0. Logical Memory: 0.0. APOEε4 alleles: 1.0. Biomarker levels: Florbetapir (AV45): 1.35 SUVR (significant elevated). ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume is severely reduced (34.5% below mean, Z-score -3.16), indicating significant neurodegeneration. Cognitive scores (MMSE 23, MoCA 15) are impaired, and elevated AV45 suggests amyloid pathology, consistent with Alzheimer's disease.  \nDiagnosis: Dementia (likely Alzheimer’s disease)  \nConfidence: High",
