  "img_finding": "Image findings: ventricular volume measures 89,507 mm³, 90.4% above the reference mean. With a Z-score of 2.63 (99.6th percentile), this represents significant enlargement; whole brain volume measures 1,132,390 mm³, 10.0% above the reference mean. With a Z-score of 1.31 (90.6th percentile), this represents mild enlargement. ",
  "text_data": "Age is 81.0 years. Gender is Male. Education: 16 years. Handedness: Right. Race: White. MMSE: 25.0. MoCA: 22.0. Logical Memory: 13.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The significant ventricular enlargement (Z-score 2.63) suggests substantial atrophy, consistent with neurodegenerative changes. The MMSE (25) and MoCA (22) scores indicate mild cognitive impairment, not severe enough for dementia. APOE4 positivity increases Alzheimer's risk.  \nDiagnosis: MCI  \nConfidence: Medium (clinical scores borderline, imaging strongly supports neurodegeneration)",
