  "img_finding": "Image findings: hippocampal volume measures 6,854 mm³, 14.6% below the reference mean. With a Z-score of -1.46 (7.2th percentile), this represents mild atrophy. ",
  "text_data": "Age is 69.9 years. Gender is Male. Education: 17 years. MMSE: 27.0. MoCA: 22.0. Logical Memory: 4.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 0.94 SUVR (mild reduced). ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume shows mild atrophy (Z-score -1.46, 7.2th percentile), which is concerning but not severe. The MMSE (27/30) is normal, but the MoCA (22/30) suggests mild cognitive impairment, particularly in executive function or attention. No APOE4 allele and mild amyloid burden (AV45) reduce the likelihood of Alzheimer's but don't rule out other causes.  \n\nDiagnosis: **MCI**  \nConfidence: **Medium** (due to conflicting MMSE/MoCA results and mild hippocampal atrophy without strong Alzheimer's biomarkers)",
