With a Z-score of 0.35 (63.8th percentile), this represents normal volume ; whole brain volume measures 1,109,720 mm³, 2.8% above the reference mean. With a Z-score of 0.36 (64.2th percentile), this represents normal volume ; entorhinal cortex volume measures 3,519 mm³, 14.2% below the reference mean. With a Z-score of -0.96 (16.8th percentile), this represents normal volume ; fusiform gyrus volume measures 19,444 mm³, 3.2% above the reference mean. With a Z-score of 0.27 (60.8th percentile), this represents normal volume ; middle temporal gyrus volume measures 23,376 mm³, 9.5% above the reference mean.

  "gpt_diagnosis": "**Reasoning:** The hippocampal, whole brain, fusiform gyrus, and middle temporal gyrus volumes are all within normal ranges, while the entorhinal cortex volume is slightly reduced but still within normal limits (Z-score -0.96). Cognitive testing (MMSE 30, MoCA 29) is intact, and there is no APOE4 genetic risk factor.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
