  "img_finding": "Image findings: ventricular volume measures 57,735 mm³, 105.7% above the reference mean. With a Z-score of 2.42 (99.2th percentile), this represents significant enlargement; whole brain volume measures 971,227 mm³, 0.4% below the reference mean. With a Z-score of -0.04 (48.2th percentile), this represents normal volume . ",
  "text_data": "Age is 74.3 years. Gender is Female. Education: 18 years. MMSE: 25.0. Logical Memory: 7.0. APOEε4 alleles: 0.0. Biomarker levels: Amyloid beta: 572.80 pg/mL (mild reduced); Total tau: 240.90 pg/mL (normal ); Phosphorylated tau: 27.33 pg/mL (normal ). ",

  "gpt_diagnosis": "Reasoning: The significant ventricular enlargement (Z-score 2.42) suggests brain atrophy, which is concerning for neurodegenerative changes. The MMSE score of 25 is borderline, and mildly reduced Aβ indicates possible early amyloid pathology, but normal tau levels and absence of APOE4 reduce the likelihood of rapid progression.  \nDiagnosis: **MCI**  \nConfidence: **Medium**",
