  "img_finding": "Image findings: ventricular volume measures 82,163 mm³, 74.8% above the reference mean. With a Z-score of 2.17 (98.5th percentile), this represents significant enlargement; whole brain volume measures 1,019,180 mm³, 1.0% below the reference mean. With a Z-score of -0.13 (44.9th percentile), this represents normal volume . ",
  "text_data": "Age is 83.0 years. Gender is Male. Education: 18 years. MMSE: 28.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is significantly enlarged (Z-score 2.17), which is often associated with brain atrophy, but the whole brain volume is within normal limits (Z-score -0.13). The MMSE score of 28 is normal, and there is no APOE4 risk allele.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (ventricular enlargement raises some concern, but other markers are normal)",
