  "img_finding": "Image findings: ventricular volume measures 107,968 mm³, 129.6% above the reference mean. With a Z-score of 3.77 (100.0th percentile), this represents profound enlargement; whole brain volume measures 1,133,400 mm³, 10.1% above the reference mean. With a Z-score of 1.33 (90.8th percentile), this represents mild enlargement. ",
  "text_data": "Age is 86.3 years. Gender is Male. Education: 16 years. MMSE: 25.0. Logical Memory: 4.0. Laboratory findings: Serum Glucose: 135.00 (profound elevated); Creatine Kinase: 214.00 (significant elevated). APOEε4 alleles: 0.0. Biomarker levels: Pittsburgh compound B: 1.71 SUVR (normal ). ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is significantly enlarged (Z-score 3.77), which is strongly indicative of brain atrophy, a hallmark of neurodegenerative disease. The MMSE score of 25 is borderline but still within normal limits for age, and the absence of APOE4 reduces genetic risk, but the profound ventricular enlargement suggests underlying pathology.  \nDiagnosis: **Mild Cognitive Impairment (MCI)**  \nConfidence: **Medium** (due to borderline MMSE but strong structural evidence of atrophy)",
