  "img_finding": "Image findings: ventricular volume measures 66,038 mm³, 71.4% above the reference mean. With a Z-score of 1.71 (95.7th percentile), this represents moderate enlargement; whole brain volume measures 1,062,200 mm³, 1.6% below the reference mean. With a Z-score of -0.21 (41.8th percentile), this represents normal volume . ",
  "text_data": "Age is 77.2 years. Gender is Male. Education: 16 years. MMSE: 28.0. Logical Memory: 4.0. Laboratory findings: Basophils: 0.00 (significant reduced). APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is moderately enlarged (71.4% above reference mean, Z-score 1.71), which can indicate atrophy, but whole brain volume is normal (Z-score -0.21). The MMSE score of 28 is within the normal range (≥26), and the presence of one APOE4 allele increases Alzheimer's risk but does not confirm impairment.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to conflicting ventricular enlargement and normal MMSE, but no clear cognitive deficits)",
