With a Z-score of -0.64 (26.1th percentile), this represents normal volume ; hippocampal volume measures 7,830 mm³, 10.1% above the reference mean. With a Z-score of 0.92 (82.2th percentile), this represents normal volume ; whole brain volume measures 953,607 mm³, 2.2% below the reference mean. With a Z-score of -0.27 (39.3th percentile), this represents normal volume ; entorhinal cortex volume measures 3,827 mm³, 4.2% above the reference mean. With a Z-score of 0.26 (60.2th percentile), this represents normal volume ; fusiform gyrus volume measures 18,902 mm³, 11.1% above the reference mean. With a Z-score of 1.01 (84.4th percentile), this represents mild enlargement; middle temporal gyrus volume measures 19,168 mm³, 0.0% below the reference mean.

  "gpt_diagnosis": "**Reasoning:** All brain volume measures (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) fall within normal ranges or show mild enlargement, with no significant atrophy. Cognitive scores (MMSE 30, MoCA 27) are within normal limits, and amyloid PET (AV45) is normal. No APOE4 risk allele is present.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
