  "img_finding": "Image findings: ventricular volume measures 39,582 mm³, 4.9% below the reference mean. With a Z-score of -0.76 (22.3th percentile), this represents normal volume ; whole brain volume measures 826,316 mm³, 9.2% below the reference mean. With a Z-score of -1.03 (15.3th percentile), this represents mild atrophy. ",
  "text_data": "Age is 90.6 years. Gender is Female. Education: 20 years. MMSE: 30.0. Logical Memory: 16.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The brain imaging shows mild atrophy in whole brain volume but normal ventricular volume. The MMSE score of 30 is within the normal range, and there is no APOE4 allele present, which reduces genetic risk for Alzheimer's.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to mild atrophy but normal cognitive scores and lack of genetic risk)",
