  "img_finding": "Image findings: ventricular volume measures 11,187 mm³, 49.9% below the reference mean. With a Z-score of -1.25 (10.6th percentile), this represents mild atrophy; hippocampal volume measures 7,520 mm³, 2.1% below the reference mean. With a Z-score of -0.24 (40.5th percentile), this represents normal volume ; whole brain volume measures 996,479 mm³, 3.2% below the reference mean. With a Z-score of -0.40 (34.6th percentile), this represents normal volume ; entorhinal cortex volume measures 3,709 mm³, 4.7% below the reference mean. With a Z-score of -0.37 (35.7th percentile), this represents normal volume ; fusiform gyrus volume measures 19,969 mm³, 9.7% above the reference mean. With a Z-score of 1.09 (86.2th percentile), this represents mild enlargement; middle temporal gyrus volume measures 21,581 mm³, 5.2% above the reference mean. With a Z-score of 0.46 (67.7th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain imaging shows mild ventricular atrophy but otherwise normal volumes in key regions (hippocampus, whole brain, entorhinal cortex). Cognitive scores (MMSE 30, MoCA 29) are intact, and there is no APOE4 genetic risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
