  "img_finding": "Image findings: ventricular volume measures 30,011 mm³, 36.2% below the reference mean. With a Z-score of -1.05 (14.7th percentile), this represents mild atrophy; whole brain volume measures 923,265 mm³, 10.3% below the reference mean. With a Z-score of -1.35 (8.9th percentile), this represents mild atrophy. ",
  "text_data": "Age is 82.4 years. Gender is Male. Education: 19 years. MMSE: 28.0. Logical Memory: 4.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The brain imaging shows mild atrophy in both ventricular and whole brain volumes, but the MMSE score of 28 is within the normal range (≥26), and there is no APOE4 genetic risk factor. Mild atrophy at this age is not uncommon and does not necessarily indicate cognitive impairment.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to mild atrophy, but strong cognitive performance and lack of genetic risk)",
