  "img_finding": "Image findings: ventricular volume measures 61,508 mm³, 59.7% above the reference mean. With a Z-score of 1.43 (92.4th percentile), this represents mild enlargement; whole brain volume measures 1,071,300 mm³, 0.8% below the reference mean. With a Z-score of -0.10 (46.1th percentile), this represents normal volume . ",
  "text_data": "Age is 76.2 years. Gender is Male. Education: 16 years. MMSE: 28.0. Logical Memory: 4.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is mildly enlarged (59.7% above reference mean, Z-score 1.43), while whole brain volume is normal (Z-score -0.10). The MMSE score of 28 is within the normal range, and the presence of one APOE4 allele increases Alzheimer's risk but does not confirm impairment.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to mild ventricular enlargement but normal cognition and brain volume)",
