  "img_finding": "Image findings: hippocampal volume measures 5,534 mm³, 26.8% below the reference mean. With a Z-score of -2.61 (0.4th percentile), this represents significant atrophy. ",
  "text_data": "Age is 78.2 years. Gender is Male. Education: 16 years. MMSE: 24.0. MoCA: 19.0. Logical Memory: 2.0. APOEε4 alleles: 2.0. Biomarker levels: Florbetapir (AV45): 1.35 SUVR (significant elevated). ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume is significantly reduced (Z-score -2.61, 0.4th percentile), indicating substantial atrophy. Combined with cognitive test scores below normal (MMSE 24, MoCA 19) and elevated amyloid burden (AV45+), this strongly suggests neurodegenerative pathology.  \nDiagnosis: **Dementia (likely Alzheimer’s disease)**  \nConfidence: **High**",
