  "img_finding": "Image findings: ventricular volume measures 70,162 mm³, 89.8% above the reference mean. With a Z-score of 2.42 (99.2th percentile), this represents significant enlargement; whole brain volume measures 879,885 mm³, 5.2% below the reference mean. With a Z-score of -0.62 (26.6th percentile), this represents normal volume . ",
  "text_data": "Age is 80.3 years. Gender is Female. Education: 17 years. MMSE: 29.0. Logical Memory: 9.0. Laboratory findings: Vitamin B12: 2332.00 (profound elevated); Eosinophils: 0.64 (profound elevated); Eosinophils: 14.30 (profound elevated). APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is significantly enlarged (Z-score 2.42), which is often associated with brain atrophy, but the whole brain volume is within normal limits (Z-score -0.62). The MMSE score of 29 is normal, and the absence of APOE4 reduces genetic risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (ventricular enlargement is notable, but cognitive performance and other markers are normal)",
