  "img_finding": "Image findings: ventricular volume measures 22,274 mm³, 39.7% below the reference mean. With a Z-score of -1.07 (14.2th percentile), this represents mild atrophy; whole brain volume measures 1,040,250 mm³, 12.1% above the reference mean. With a Z-score of 1.45 (92.6th percentile), this represents mild enlargement. ",

  "gpt_diagnosis": "Reasoning: The MMSE score of 29 is within the normal range (≥26), and there is no significant cognitive impairment reported. The mild ventricular atrophy is not severe enough to indicate dementia, and the whole brain volume is actually above average. The absence of APOE4 also reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
