  "img_finding": "Image findings: ventricular volume measures 58,166 mm³, 107.2% above the reference mean. With a Z-score of 2.46 (99.3th percentile), this represents significant enlargement; whole brain volume measures 970,248 mm³, 0.5% below the reference mean. With a Z-score of -0.06 (47.7th percentile), this represents normal volume . ",
  "text_data": "Age is 73.6 years. Gender is Female. Education: 12 years. MMSE: 25.0. MoCA: 23.0. Logical Memory: 10.0. APOEε4 alleles: 0.0. Biomarker levels: Flobetaben (FBB): 1.03 SUVR (normal ). ",

  "gpt_diagnosis": "Reasoning: The significant ventricular enlargement (Z-score 2.46) suggests possible brain atrophy, while whole brain volume remains normal. The MMSE and MoCA scores are borderline (mild cognitive impairment range), but the absence of APOE4 reduces genetic risk.  \nDiagnosis: MCI  \nConfidence: Medium",
