  "img_finding": "Image findings: ventricular volume measures 74,689 mm³, 102.1% above the reference mean. With a Z-score of 2.75 (99.7th percentile), this represents significant enlargement; whole brain volume measures 919,346 mm³, 1.0% below the reference mean. With a Z-score of -0.11 (45.5th percentile), this represents normal volume . ",
  "text_data": "Age is 81.3 years. Gender is Female. Education: 12 years. MMSE: 23.0. Logical Memory: 0.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The significant ventricular enlargement (Z-score 2.75) suggests substantial atrophy, consistent with neurodegenerative processes. The MMSE score of 23.0 indicates mild cognitive impairment, and the presence of one APOE4 allele increases Alzheimer's risk.  \nDiagnosis: Dementia (likely Alzheimer's type)  \nConfidence: Medium (clinical correlation and biomarker confirmation would strengthen certainty)",
