  "img_finding": "Image findings: ventricular volume measures 54,173 mm³, 46.6% above the reference mean. With a Z-score of 1.26 (89.6th percentile), this represents mild enlargement; whole brain volume measures 902,292 mm³, 2.8% below the reference mean. With a Z-score of -0.33 (36.9th percentile), this represents normal volume . ",
  "text_data": "Age is 81.6 years. Gender is Female. Education: 12 years. MMSE: 25.0. Logical Memory: 0.0. Laboratory findings: Vitamin B12: 1076.00 (significant elevated); Neutrophils: 78.70 (significant elevated); Neutrophils: 6.82 (significant elevated); Serum Glucose: 164.00 (profound elevated); Serum Uric Acid: 2.60 (significant reduced). APOEε4 alleles: 2.0. Biomarker levels: Pittsburgh compound B: 1.84 SUVR (normal ). ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is mildly enlarged (46.6% above reference mean), suggesting possible atrophy, while whole brain volume is within normal limits. The MMSE score of 25 is borderline, and the presence of two APOE4 alleles increases Alzheimer's risk.  \nDiagnosis: **MCI (Mild Cognitive Impairment)**  \nConfidence: **Medium** (MMSE is near the cutoff, and imaging shows mild but not definitive atrophy)",
