  "img_finding": "Image findings: hippocampal volume measures 6,659 mm³, 11.9% below the reference mean. With a Z-score of -1.16 (12.3th percentile), this represents mild atrophy. ",
  "text_data": "Age is 72.1 years. Gender is Male. Education: 14 years. MMSE: 11.0. APOEε4 alleles: 1.0. Biomarker levels: Florbetapir (AV45): 1.43 SUVR (significant elevated). ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume is mildly reduced (Z-score -1.16, 12.3th percentile), and the MMSE score of 11 indicates severe cognitive impairment. Elevated AV45 (amyloid PET) and APOE4 positivity further support Alzheimer's pathology.  \nDiagnosis: Dementia (likely Alzheimer’s disease)  \nConfidence: High",
