  "img_finding": "Image findings: ventricular volume measures 58,332 mm³, 51.4% above the reference mean. With a Z-score of 1.23 (89.1th percentile), this represents mild enlargement; whole brain volume measures 1,050,680 mm³, 2.7% below the reference mean. With a Z-score of -0.35 (36.5th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is mildly enlarged (Z-score 1.23), while whole brain volume is within normal limits (Z-score -0.35). Cognitive scores (MMSE 26, MoCA 23) suggest mild cognitive impairment, and the presence of one APOE4 allele increases Alzheimer's risk.  \nDiagnosis: **MCI**  \nConfidence: **Medium** (Cognitive scores align with MCI, but structural changes are not severe enough for dementia.)",
