  "img_finding": "Image findings: ventricular volume measures 56,030 mm³, 19.2% above the reference mean. With a Z-score of 0.56 (71.1th percentile), this represents normal volume ; whole brain volume measures 964,403 mm³, 6.3% below the reference mean. With a Z-score of -0.82 (20.5th percentile), this represents normal volume . ",
  "text_data": "Age is 81.1 years. Gender is Male. Education: 18 years. MMSE: 27.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is slightly above the reference mean but still within normal range (Z-score 0.56), while the whole brain volume is slightly below the reference mean but also within normal range (Z-score -0.82). The MMSE score of 27 is within the normal range for cognitive function, and the absence of APOE4 alleles reduces genetic risk for Alzheimer's.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (while the metrics are normal, age-related changes could still be a factor, and clinical correlation would be helpful for higher confidence)",
