  "img_finding": "Image findings: ventricular volume measures 66,665 mm³, 36.4% above the reference mean. With a Z-score of 3.30 (100.0th percentile), this represents profound enlargement; whole brain volume measures 992,631 mm³, 0.9% below the reference mean. With a Z-score of -0.15 (43.9th percentile), this represents normal volume . ",
  "text_data": "Age is 90.5 years. Gender is Male. Education: 20 years. MMSE: 29.0. MoCA: 24.0. Logical Memory: 11.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is significantly enlarged (Z-score 3.30), which is often associated with neurodegenerative processes, but the whole brain volume is within normal limits (Z-score -0.15). Cognitive scores are mixed (MMSE 29.0 is normal, MoCA 24.0 suggests mild impairment), but the absence of APOE4 and high MMSE score argue against significant dementia.  \nDiagnosis: **MCI** (Mild Cognitive Impairment)  \nConfidence: **Medium** (due to conflicting cognitive scores and significant ventricular enlargement but preserved global brain volume)",
