With a Z-score of -0.98 (16.4th percentile), this represents normal volume ; hippocampal volume measures 8,315 mm³, 8.2% above the reference mean. With a Z-score of 0.92 (82.1th percentile), this represents normal volume ; whole brain volume measures 1,025,130 mm³, 0.4% below the reference mean. With a Z-score of -0.05 (48.1th percentile), this represents normal volume ; entorhinal cortex volume measures 4,061 mm³, 4.3% above the reference mean. With a Z-score of 0.33 (63.1th percentile), this represents normal volume ; fusiform gyrus volume measures 19,796 mm³, 8.7% above the reference mean. With a Z-score of 0.98 (83.7th percentile), this represents normal volume ; middle temporal gyrus volume measures 19,923 mm³, 2.9% below the reference mean.

  "gpt_diagnosis": "**Reasoning:** All brain volume measures (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, middle temporal gyrus) fall within normal ranges based on Z-scores and percentiles. Cognitive scores (MMSE 29, MoCA 28) are intact, and amyloid PET (AV45) is normal. No APOE4 risk alleles are present.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
