  "img_finding": "Image findings: hippocampal volume measures 7,176 mm³, 3.0% above the reference mean. With a Z-score of 0.26 (60.2th percentile), this represents normal volume . ",
  "text_data": "Age is 82.3 years. Gender is Male. Education: 12 years. MMSE: 22.0. MoCA: 19.0. Logical Memory: 7.0. APOEε4 alleles: 1.0. Biomarker levels: Florbetapir (AV45): 1.22 SUVR (mild elevated). ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume is within normal range, but cognitive scores (MMSE: 22, MoCA: 19) are below typical thresholds for normal cognition, suggesting cognitive impairment. The presence of mild amyloid elevation (AV45) and one APOE4 allele increases the likelihood of neurodegenerative pathology.  \nDiagnosis: **MCI**  \nConfidence: **Medium** (Cognitive scores indicate impairment, but hippocampal volume is preserved, and amyloid burden is only mild.)",
