  "img_finding": "Image findings: hippocampal volume measures 7,984 mm³, 5.6% above the reference mean. With a Z-score of 0.55 (70.8th percentile), this represents normal volume ; whole brain volume measures 1,265,260 mm³, 17.2% above the reference mean. With a Z-score of 2.24 (98.7th percentile), this represents significant enlargement; entorhinal cortex volume measures 4,075 mm³, 0.6% below the reference mean. With a Z-score of -0.04 (48.3th percentile), this represents normal volume ; fusiform gyrus volume measures 20,749 mm³, 10.1% above the reference mean. With a Z-score of 0.86 (80.6th percentile), this represents normal volume ; middle temporal gyrus volume measures 22,181 mm³, 3.9% above the reference mean. With a Z-score of 0.35 (63.9th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The hippocampal, entorhinal cortex, fusiform gyrus, and middle temporal gyrus volumes are all within normal ranges (Z-scores close to 0 or slightly above). The whole brain volume is significantly enlarged, which is atypical for Alzheimer's but not indicative of neurodegeneration. Cognitive scores (MMSE 30, MoCA 27) are normal for age, and the absence of APOE4 further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
