  "img_finding": "Image findings: ventricular volume measures 20,860 mm³, 45.8% below the reference mean. With a Z-score of -1.10 (13.6th percentile), this represents mild atrophy; hippocampal volume measures 8,431 mm³, 11.5% above the reference mean. With a Z-score of 1.13 (87.0th percentile), this represents mild enlargement; whole brain volume measures 1,172,270 mm³, 8.6% above the reference mean. With a Z-score of 1.12 (86.8th percentile), this represents mild enlargement; entorhinal cortex volume measures 4,669 mm³, 13.9% above the reference mean. With a Z-score of 0.94 (82.6th percentile), this represents normal volume ; fusiform gyrus volume measures 18,746 mm³, 0.5% below the reference mean. With a Z-score of -0.04 (48.3th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,598 mm³, 1.2% above the reference mean. With a Z-score of 0.11 (54.3th percentile), this represents normal volume . ",

  "gpt_diagnosis": "**Reasoning:** The brain volume data shows mild ventricular enlargement (consistent with mild atrophy) but otherwise normal-to-above-average volumes in key regions (hippocampus, whole brain, entorhinal cortex, fusiform gyrus, middle temporal gyrus). The MMSE score of 30/30 is intact, and the absence of APOE4 alleles reduces genetic risk. No cognitive deficits are reported.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
