With a Z-score of -0.23 (40.9th percentile), this represents normal volume ; hippocampal volume measures 7,611 mm³, 1.0% below the reference mean. With a Z-score of -0.11 (45.7th percentile), this represents normal volume ; whole brain volume measures 1,070,370 mm³, 4.0% above the reference mean. With a Z-score of 0.50 (69.1th percentile), this represents normal volume ; entorhinal cortex volume measures 3,706 mm³, 4.8% below the reference mean. With a Z-score of -0.37 (35.5th percentile), this represents normal volume ; fusiform gyrus volume measures 18,422 mm³, 1.2% above the reference mean. With a Z-score of 0.13 (55.2th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,580 mm³, 5.2% above 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 screening scores (MMSE 27, MoCA 24) are within normal limits for age, and amyloid PET (AV45) is normal. No APOE4 risk allele is present.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
