  "img_finding": "Image findings: ventricular volume measures 59,070 mm³, 53.4% above the reference mean. With a Z-score of 1.28 (89.9th percentile), this represents mild enlargement; whole brain volume measures 1,042,560 mm³, 3.4% below the reference mean. With a Z-score of -0.44 (32.9th percentile), this represents normal volume . ",
  "text_data": "Age is 77.9 years. Gender is Male. Education: 16 years. MMSE: 27.0. Logical Memory: 0.0. APOEε4 alleles: 0.0. Biomarker levels: Amyloid beta: 1443.00 pg/mL (mild elevated); Total tau: 264.70 pg/mL (normal ); Phosphorylated tau: 24.36 pg/mL (normal ). ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is mildly enlarged, which can be associated with brain atrophy, but the whole brain volume is within normal limits. The MMSE score of 27 is normal, and biomarkers (Aβ mildly elevated, normal tau) do not strongly support Alzheimer's pathology.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to mild ventricular enlargement and elevated Aβ, but normal cognition and tau levels)",
