  "img_finding": "Image findings: ventricular volume measures 51,045 mm³, 8.6% above the reference mean. With a Z-score of 0.25 (59.8th percentile), this represents normal volume ; whole brain volume measures 1,003,660 mm³, 2.5% below the reference mean. With a Z-score of -0.32 (37.3th percentile), this represents normal volume . ",
  "text_data": "Age is 80.2 years. Gender is Male. Education: 16 years. MMSE: 23.0. Logical Memory: 3.0. APOEε4 alleles: 0.0. Biomarker levels: Amyloid beta: 1657.00 pg/mL (moderate elevated); Total tau: 213.90 pg/mL (normal ); Phosphorylated tau: 19.68 pg/mL (normal ). ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is slightly above the reference mean but still within normal range (Z-score 0.25), while whole brain volume is slightly below the reference mean but also normal (Z-score -0.32). The MMSE score of 23 suggests mild cognitive impairment, and moderate Aβ elevation indicates amyloid pathology, though tau markers are normal.  \nDiagnosis: MCI  \nConfidence: Medium",
