With a Z-score of 0.44 (66.9th percentile), this represents normal volume ; whole brain volume measures 1,055,750 mm³, 2.2% below the reference mean. With a Z-score of -0.28 (38.8th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is slightly above the reference mean but still within normal range (Z-score 0.44), and whole brain volume is slightly below the reference mean but also normal (Z-score -0.28). The MMSE score of 22 suggests mild cognitive impairment, but the absence of APOE4 and normal brain volumes reduce the likelihood of dementia.  \nDiagnosis: MCI  \nConfidence: Medium",
