  "img_finding": "Image findings: ventricular volume measures 67,645 mm³, 141.0% above the reference mean. With a Z-score of 3.23 (99.9th percentile), this represents profound enlargement; whole brain volume measures 901,451 mm³, 7.5% below the reference mean. With a Z-score of -0.95 (17.2th percentile), this represents normal volume . ",
  "text_data": "Age is 70.8 years. Gender is Female. Education: 20 years. MMSE: 20.0. APOEε4 alleles: 1.0. ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is significantly enlarged (141% above the mean, Z-score 3.23), indicating substantial atrophy, while whole brain volume is only slightly reduced (7.5% below mean, Z-score -0.95). The MMSE score of 20 suggests cognitive impairment, and the presence of one APOE4 allele increases Alzheimer's risk.  \nDiagnosis: **Dementia** (likely Alzheimer's disease given structural and cognitive findings)  \nConfidence: **High**",
