With a Z-score of 0.79 (78.4th percentile), this represents normal volume ; whole brain volume measures 1,152,810 mm³, 12.0% above the reference mean. With a Z-score of 1.50 (93.3th percentile), this represents mild enlargement. ",

  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is within normal limits, and the whole brain volume is mildly enlarged, which is atypical for neurodegeneration. The MMSE score of 30 is intact, and the absence of APOE4 further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
