  "img_finding": "Image findings: ventricular volume measures 64,864 mm³, 38.0% above the reference mean. With a Z-score of 1.10 (86.5th percentile), this represents mild enlargement; whole brain volume measures 970,430 mm³, 5.7% below the reference mean. With a Z-score of -0.75 (22.7th percentile), this represents normal volume . ",
  "text_data": "Age is 81.6 years. Gender is Male. Education: 20 years. MMSE: 26.0. Logical Memory: 0.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is mildly enlarged (38.0% above reference mean, Z-score 1.10), while whole brain volume is slightly reduced but still within normal range (Z-score -0.75). The MMSE score of 26 is borderline, and the presence of one APOE4 allele increases Alzheimer's risk.  \nDiagnosis: **MCI (Mild Cognitive Impairment)**  \nConfidence: **Medium** (MMSE is near the cutoff, and structural changes are mild but notable for age).",
