With a Z-score of 0.43 (66.6th percentile), this represents normal volume ; hippocampal volume measures 8,738 mm³, 8.9% above the reference mean. With a Z-score of 0.89 (81.2th percentile), this represents normal volume ; whole brain volume measures 1,098,450 mm³, 3.2% below the reference mean. With a Z-score of -0.45 (32.6th percentile), this represents normal volume ; entorhinal cortex volume measures 3,886 mm³, 8.8% below the reference mean. With a Z-score of -0.61 (27.0th percentile), this represents normal volume ; fusiform gyrus volume measures 18,465 mm³, 7.3% below the reference mean. With a Z-score of -0.60 (27.3th percentile), this represents normal volume ; middle temporal gyrus volume measures 20,616 mm³, 8.0% below the reference mean. With a Z-score of -0.66 (25.5th 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 assessments (MMSE 30, MoCA 29) are intact, and there is no APOE4 genetic risk factor.  \n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
