  "img_finding": "Image findings: ventricular volume measures 29,721 mm³, 36.8% below the reference mean. With a Z-score of -1.07 (14.3th percentile), this represents mild atrophy; whole brain volume measures 969,576 mm³, 5.8% below the reference mean. With a Z-score of -0.76 (22.4th percentile), this represents normal volume . ",
  "text_data": "Age is 81.2 years. Gender is Male. Education: 16 years. MMSE: 26.0. Logical Memory: 0.0. APOEε4 alleles: 2.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The ventricular volume shows mild atrophy, but whole brain volume is within normal limits. The MMSE score of 26 is borderline but still within the normal range for age, and the presence of two APOE4 alleles increases Alzheimer's risk but does not confirm impairment.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to borderline MMSE and APOE4 status, but no clear cognitive decline or significant atrophy)",
