With a Z-score of 1.51 (93.4th percentile), this represents moderate enlargement; whole brain volume measures 1,012,580 mm³, 6.2% below the reference mean. With a Z-score of -0.80 (21.1th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is moderately enlarged (62.9% above reference mean, Z-score 1.51), suggesting possible atrophy, while whole brain volume is within normal limits (Z-score -0.80). The MMSE score of 23 indicates mild cognitive impairment, and the presence of one APOE4 allele increases Alzheimer's risk.  \nDiagnosis: MCI  \nConfidence: Medium",
