With a Z-score of -0.69 (24.4th percentile), this represents normal volume ; hippocampal volume measures 7,364 mm³, 4.2% below the reference mean. With a Z-score of -0.47 (32.0th percentile), this represents normal volume ; whole brain volume measures 958,167 mm³, 6.9% below the reference mean. With a Z-score of -0.86 (19.5th percentile), this represents normal volume ; entorhinal cortex volume measures 3,455 mm³, 11.2% below the reference mean. With a Z-score of -0.87 (19.2th percentile), this represents normal volume ; fusiform gyrus volume measures 19,184 mm³, 5.3% above the reference mean. With a Z-score of 0.60 (72.6th percentile), this represents normal volume ; middle temporal gyrus volume measures 19,813 mm³, 3.4% below the reference mean.

  "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 scores (MMSE 29, MoCA 27) are within normal limits, and the absence of APOE4 further reduces Alzheimer's risk.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
