  "img_finding": "Image findings: hippocampal volume measures 8,772 mm³, 9.3% above the reference mean. With a Z-score of 0.93 (82.3th percentile), this represents normal volume . ",
  "text_data": "Age is 63.5 years. Gender is Male. Education: 18 years. MMSE: 29.0. MoCA: 24.0. Logical Memory: 8.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume is within normal range (Z-score 0.93), and cognitive screening scores (MMSE 29, MoCA 24) are borderline but not strongly indicative of impairment. The presence of one APOE4 allele increases risk but does not confirm pathology.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to borderline MoCA score but otherwise normal biomarkers)",
