  "img_finding": "Image findings: ventricular volume measures 82,089 mm³, 192.5% above the reference mean. With a Z-score of 4.41 (100.0th percentile), this represents profound enlargement; whole brain volume measures 718,487 mm³, 26.3% below the reference mean. With a Z-score of -3.31 (0.0th percentile), this represents profound atrophy. ",
  "text_data": "Age is 73.3 years. Gender is Female. Education: 16 years. MMSE: 25.0. APOEε4 alleles: 2.0. ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The data shows profound ventricular enlargement and whole brain atrophy, both significantly beyond normal ranges (Z-scores of 4.41 and -3.31, respectively). The MMSE score of 25 is borderline, and the presence of two APOE4 alleles increases Alzheimer's risk.  \nDiagnosis: Dementia (likely Alzheimer's disease)  \nConfidence: Medium (clinical correlation and biomarker confirmation would strengthen certainty)",
