  "img_finding": "Image findings: ventricular volume measures 72,735 mm³, 88.8% above the reference mean. With a Z-score of 2.13 (98.3th percentile), this represents significant enlargement; whole brain volume measures 1,013,600 mm³, 6.1% below the reference mean. With a Z-score of -0.79 (21.4th percentile), this represents normal volume . ",
  "text_data": "Age is 75.9 years. Gender is Male. Education: 12 years. MMSE: 29.0. Laboratory findings: Hematocrit: 49.00 (significant elevated); RBC: 5.50 (significant elevated); Hemoglobin: 16.60 (significant elevated); Total Bilirubin: 1.30 (profound elevated); Alkaline Phosphatase: 142.00 (profound elevated); Direct Bilirubin: 0.30 (significant elevated). APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is significantly enlarged (Z-score 2.13), which is often associated with brain atrophy, but the whole brain volume is within normal limits (Z-score -0.79). The MMSE score of 29 is normal, and there is no APOE4 genetic risk factor.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (ventricular enlargement raises some concern, but normal MMSE and brain volume suggest no significant impairment)",
