  "img_finding": "Image findings: ventricular volume measures 117,488 mm³, 149.9% above the reference mean. With a Z-score of 4.35 (100.0th percentile), this represents profound enlargement; whole brain volume measures 1,019,160 mm³, 1.0% below the reference mean. With a Z-score of -0.13 (44.9th percentile), this represents normal volume . ",
  "text_data": "Age is 82.6 years. Gender is Male. Education: 14 years. MMSE: 29.0. MoCA: 21.0. Logical Memory: 12.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is significantly enlarged (Z-score 4.35), suggesting substantial atrophy, while whole brain volume is within normal limits. Despite high MMSE (29), the MoCA score (21) indicates mild cognitive impairment, and the presence of APOE4 increases Alzheimer's risk.  \nDiagnosis: **MCI**  \nConfidence: **Medium** (ventricular enlargement and MoCA support MCI, but MMSE is unexpectedly high for typical MCI)",
