  "img_finding": "Image findings: ventricular volume measures 59,256 mm³, 111.1% above the reference mean. With a Z-score of 2.54 (99.5th percentile), this represents significant enlargement; whole brain volume measures 877,444 mm³, 10.0% below the reference mean. With a Z-score of -1.26 (10.5th percentile), this represents mild atrophy. ",

  "gpt_diagnosis": "Reasoning: The significant ventricular enlargement (Z-score 2.54) and mild whole brain atrophy (Z-score -1.26) indicate structural brain changes consistent with neurodegeneration. The MMSE score of 23.0 suggests mild cognitive impairment, and the absence of APOE4 reduces but does not eliminate Alzheimer's risk.  \nDiagnosis: MCI  \nConfidence: Medium",
