With a Z-score of 1.43 (92.4th percentile), this represents mild enlargement; whole brain volume measures 1,025,320 mm³, 5.0% below the reference mean. With a Z-score of -0.65 (25.8th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is mildly enlarged (59.7% above reference mean, Z-score 1.43), while whole brain volume is within normal limits (5.0% below reference mean, Z-score -0.65). The MMSE score of 25 is borderline, but the absence of APOE4 and relatively preserved brain volume suggest mild cognitive changes rather than dementia.  \nDiagnosis: **MCI**  \nConfidence: **Medium**",
