  "img_finding": "Image findings: ventricular volume measures 62,035 mm³, 61.1% above the reference mean. With a Z-score of 1.46 (92.8th percentile), this represents mild enlargement; whole brain volume measures 1,000,820 mm³, 7.3% below the reference mean. With a Z-score of -0.95 (17.2th percentile), this represents normal volume . ",
  "text_data": "Age is 71.0 years. Gender is Male. Education: 15 years. MMSE: 27.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is mildly enlarged (61.1% above reference mean), while whole brain volume is within normal limits (7.3% below reference mean). The MMSE score of 27 is within the normal range, and there is no APOE4 genetic risk factor.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (mild ventricular enlargement could suggest early changes, but cognitive performance remains intact)",
