With a Z-score of 0.47 (68.2th percentile), this represents normal volume ; hippocampal volume measures 8,139 mm³, 5.9% above the reference mean. With a Z-score of 0.66 (74.7th percentile), this represents normal volume ; whole brain volume measures 1,036,620 mm³, 0.7% above the reference mean. With a Z-score of 0.09 (53.6th percentile), this represents normal volume ; entorhinal cortex volume measures 3,427 mm³, 12.0% below the reference mean. With a Z-score of -0.93 (17.7th percentile), this represents normal volume ; fusiform gyrus volume measures 16,708 mm³, 8.2% below the reference mean. With a Z-score of -0.93 (17.6th percentile), this represents normal volume ; middle temporal gyrus volume measures 19,882 mm³, 3.1% below the reference mean. With a Z-score of -0.28 (39.1th percentile), this represents normal volume . ",

  "gpt_diagnosis": "**Reasoning:** All brain volumes (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) fall within normal ranges based on Z-scores and percentiles. Cognitive screening (MMSE 30, MoCA 29) is intact, and there is no APOE4 genetic risk factor.  \n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
