  "img_finding": "Image findings: ventricular volume measures 26,321 mm³, 17.8% above the reference mean. With a Z-score of 0.45 (67.2th percentile), this represents normal volume ; whole brain volume measures 1,275,790 mm³, 24.0% above the reference mean. With a Z-score of 2.98 (99.9th percentile), this represents significant enlargement. ",
  "text_data": "Age is 62.8 years. Gender is Female. Education: 16 years. MMSE: 28.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is within normal limits, and the whole brain volume is significantly above average, which is atypical for Alzheimer's. The MMSE score of 28 is within the normal range, and the presence of one APOE4 allele alone does not confirm pathology.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to the unusual brain volume enlargement, though cognitive scores are normal)",
