  "img_finding": "Image findings: ventricular volume measures 29,037 mm³, 3.5% above the reference mean. With a Z-score of 0.08 (53.2th percentile), this represents normal volume ; whole brain volume measures 1,041,880 mm³, 6.9% above the reference mean. With a Z-score of 0.87 (80.7th percentile), this represents normal volume ; entorhinal cortex volume measures 4,532 mm³, 23.4% above the reference mean. With a Z-score of 1.44 (92.4th percentile), this represents mild enlargement; fusiform gyrus volume measures 16,979 mm³, 0.2% below the reference mean. With a Z-score of -0.02 (49.3th percentile), this represents normal volume ; middle temporal gyrus volume measures 18,245 mm³, 4.8% below the reference mean. With a Z-score of -0.42 (33.8th percentile), this represents normal volume . ",

  "gpt_diagnosis": "**Reasoning:** The brain volume measures are largely within normal ranges, with only mild enlargement noted in the entorhinal cortex. Cognitive scores (MMSE 30, MoCA 27) are within normal limits for age, and there is no APOE4 genetic risk factor. No significant atrophy or cognitive impairment is evident.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
