  "img_finding": "Image findings: ventricular volume measures 32,957 mm³, 10.8% below the reference mean. With a Z-score of -0.29 (38.5th percentile), this represents normal volume ; whole brain volume measures 943,110 mm³, 1.6% above the reference mean. With a Z-score of 0.19 (57.7th percentile), this represents normal volume . ",
  "text_data": "Age is 83.6 years. Gender is Female. Education: 14 years. MMSE: 30.0. Logical Memory: 9.0. APOEε4 alleles: 0.0. Biomarker levels: Amyloid beta: 1479.00 pg/mL (mild elevated); Total tau: 241.10 pg/mL (normal ); Phosphorylated tau: 20.28 pg/mL (normal ). ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, and the MMSE score of 30 is intact. While Aβ is mildly elevated, T-tau and P-tau are normal, suggesting no strong evidence of neurodegeneration.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to mildly elevated Aβ, but no other supporting biomarkers or cognitive deficits)",
