  "img_finding": "Image findings: hippocampal volume measures 6,902 mm³, 3.0% below the reference mean. With a Z-score of -0.27 (39.2th percentile), this represents normal volume ; whole brain volume measures 1,088,380 mm³, 11.7% above the reference mean. With a Z-score of 1.47 (92.9th percentile), this represents mild enlargement. ",
  "text_data": "Age is 75.0 years. Gender is Female. Education: 16 years. MMSE: 25.0. MoCA: 19.0. Logical Memory: 0.0. APOEε4 alleles: 1.0. ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume is within normal limits (Z-score -0.27), and whole brain volume is mildly enlarged (Z-score 1.47). However, cognitive testing shows borderline impairment (MMSE 25, MoCA 19), which is concerning for possible cognitive decline, especially given the APOE4 carrier status.  \nDiagnosis: **MCI** (Mild Cognitive Impairment)  \nConfidence: **Medium** (Cognitive scores suggest impairment, but structural brain changes are not strongly supportive of neurodegeneration.)",
