With a Z-score of 1.28 (89.9th percentile), this represents mild enlargement; whole brain volume measures 1,031,310 mm³, 4.5% below the reference mean. With a Z-score of -0.58 (28.2th percentile), this represents normal volume . ",
  "text_data": "Age is 78.9 years. Gender is Male. Education: 16 years. MMSE: 25.0. Logical Memory: 0.0. Laboratory findings: RBC: 5.50 (significant elevated); GGT: 44.00 (significant elevated). APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is mildly enlarged (53.3% above reference mean), suggesting possible atrophy, while whole brain volume is within normal limits. The MMSE score of 25 is borderline, but the absence of APOE4 reduces genetic risk.  \nDiagnosis: **Mild Cognitive Impairment (MCI)**  \nConfidence: **Medium** (MMSE is borderline, imaging shows mild atrophy, but no strong genetic risk factors)",
