  "img_finding": "Image findings: ventricular volume measures 23,002 mm³, 40.3% below the reference mean. With a Z-score of -0.96 (16.7th percentile), this represents normal volume ; hippocampal volume measures 8,613 mm³, 13.9% above the reference mean. With a Z-score of 1.36 (91.3th percentile), this represents mild enlargement; whole brain volume measures 1,179,880 mm³, 9.3% above the reference mean. With a Z-score of 1.21 (88.7th percentile), this represents mild enlargement; entorhinal cortex volume measures 4,033 mm³, 1.6% below the reference mean. With a Z-score of -0.11 (45.6th percentile), this represents normal volume ; fusiform gyrus volume measures 18,172 mm³, 3.5% below the reference mean. With a Z-score of -0.30 (38.2th percentile), this represents normal volume ; middle temporal gyrus volume measures 25,486 mm³, 19.4% above the reference mean. With a Z-score of 1.75 (96.0th percentile), this represents moderate enlargement. ",

  "gpt_diagnosis": "Reasoning: The brain volume measurements show normal or enlarged volumes in key regions (hippocampus, whole brain, middle temporal gyrus), with no significant atrophy. Cognitive scores (MMSE 29, MoCA 26) are within normal limits for age, and the absence of APOE4 further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
