  "img_finding": "Image findings: ventricular volume measures 46,531 mm³, 25.9% above the reference mean. With a Z-score of 0.70 (75.8th percentile), this represents normal volume ; whole brain volume measures 918,945 mm³, 1.0% below the reference mean. With a Z-score of -0.12 (45.2th percentile), this represents normal volume . ",
  "text_data": "Age is 80.1 years. Gender is Female. Education: 12 years. MMSE: 29.0. APOEε4 alleles: 2.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is slightly above the reference mean but still within normal range (Z-score 0.70), and whole brain volume is minimally below the reference mean (Z-score -0.12), both indicating no significant atrophy. The MMSE score of 29 is within the normal range, and while the presence of two APOE4 alleles increases Alzheimer's risk, there are no current cognitive deficits.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to normal imaging and MMSE, but APOE4 status warrants caution for future monitoring)",
