  "img_finding": "Image findings: ventricular volume measures 28,886 mm³, 21.9% below the reference mean. With a Z-score of -0.59 (27.8th percentile), this represents normal volume ; whole brain volume measures 1,076,780 mm³, 16.0% above the reference mean. With a Z-score of 1.92 (97.3th percentile), this represents moderate enlargement. ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is within normal limits, and the whole brain volume is moderately enlarged, which is atypical for Alzheimer's but not indicative of neurodegeneration. Cognitive scores (MMSE 29, MoCA 27) are in the normal range, and the absence of APOE4 further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
