With a Z-score of -0.84 (20.2th percentile), this represents normal volume ; hippocampal volume measures 6,813 mm³, 2.2% below the reference mean. With a Z-score of -0.19 (42.4th percentile), this represents normal volume ; whole brain volume measures 1,012,090 mm³, 1.7% below the reference mean. With a Z-score of -0.22 (41.4th percentile), this represents normal volume ; entorhinal cortex volume measures 4,141 mm³, 4.3% above the reference mean. With a Z-score of 0.28 (61.2th percentile), this represents normal volume ; fusiform gyrus volume measures 16,040 mm³, 11.2% below the reference mean. With a Z-score of -0.97 (16.6th percentile), this represents normal volume ; middle temporal gyrus volume measures 17,983 mm³, 10.9% below the reference mean. With a Z-score of -0.97 (16.5th percentile), this represents normal volume . ",

  "gpt_diagnosis": "**Reasoning:** All brain volume measures (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) fall within normal ranges based on Z-scores and percentiles. The MMSE score of 29/30 is within the normal range, and there is no APOE4 genetic risk factor.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
