With a Z-score of 0.60 (72.6th percentile), this represents normal volume ; hippocampal volume measures 7,514 mm³, 5.6% above the reference mean. With a Z-score of 0.52 (69.7th percentile), this represents normal volume ; whole brain volume measures 983,672 mm³, 0.9% above the reference mean. With a Z-score of 0.12 (54.6th percentile), this represents normal volume ; entorhinal cortex volume measures 3,752 mm³, 2.2% above the reference mean. With a Z-score of 0.13 (55.3th percentile), this represents normal volume ; fusiform gyrus volume measures 16,117 mm³, 5.3% below the reference mean. With a Z-score of -0.48 (31.6th percentile), this represents normal volume ; middle temporal gyrus volume measures 20,618 mm³, 7.6% above the reference mean.

  "gpt_diagnosis": "**Reasoning:** All brain volumes (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) are within normal ranges based on Z-scores and percentiles. Cognitive scores (MMSE 29, MoCA 28) are also normal, and there is no APOE4 risk allele. No significant atrophy or cognitive impairment is evident.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
