  "img_finding": "Image findings: ventricular volume measures 82,915 mm³, 115.3% above the reference mean. With a Z-score of 2.76 (99.7th percentile), this represents significant enlargement; whole brain volume measures 866,962 mm³, 19.7% below the reference mean. With a Z-score of -2.55 (0.5th percentile), this represents significant atrophy. ",
  "text_data": "Age is 78.3 years. Gender is Male. Education: 10 years. MMSE: 25.0. MoCA: 22.0. Logical Memory: 5.0. Biomarker levels: Flobetaben (FBB): 1.50 SUVR (profound elevated). ",

  "gpt_diagnosis": "**Reasoning:** The data shows significant ventricular enlargement (115.3% above mean, Z-score 2.76) and whole brain atrophy (19.7% below mean, Z-score -2.55), both strongly indicative of neurodegeneration. The cognitive scores (MMSE 25, MoCA 22) suggest mild impairment but not severe dementia.  \n\n**Diagnosis:** **Mild Cognitive Impairment (MCI)** (likely progressing toward dementia given the structural changes)  \n\n**Confidence:** **High** (due to clear imaging abnormalities and borderline cognitive scores)",
