  "img_finding": "Image findings: ventricular volume measures 49,911 mm³, 6.2% above the reference mean. With a Z-score of 0.18 (57.1th percentile), this represents normal volume ; whole brain volume measures 953,508 mm³, 7.4% below the reference mean. With a Z-score of -0.96 (16.8th percentile), this represents normal volume . ",
  "text_data": "Age is 84.6 years. Gender is Male. Education: 16 years. MMSE: 28.0. 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 0.18), while the whole brain volume is slightly below the reference mean but also within normal range (Z-score -0.96). The MMSE score of 28 is within the normal range, and there is no APOE4 allele present, which reduces Alzheimer's risk.  \n\nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to borderline brain volume changes, but strong cognitive performance and lack of genetic risk)",
