  "img_finding": "Image findings: ventricular volume measures 35,464 mm³, 26.4% above the reference mean. With a Z-score of 0.60 (72.7th percentile), this represents normal volume ; whole brain volume measures 798,127 mm³, 18.1% below the reference mean. With a Z-score of -2.28 (1.1th percentile), this represents significant atrophy. ",
  "text_data": "Age is 79.8 years. Gender is Female. Education: 18 years. MMSE: 26.0. Logical Memory: 0.0. APOEε4 alleles: 0.0. Biomarker levels: Pittsburgh compound B: 2.12 SUVR (mild elevated). ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The patient shows significant whole brain atrophy (Z-score -2.28, 1.1th percentile) but normal ventricular volume. The MMSE score of 26 is borderline, and the absence of APOE4 reduces genetic risk.  \nDiagnosis: MCI (Mild Cognitive Impairment)  \nConfidence: Medium",
