With a Z-score of -0.59 (27.8th percentile), this represents normal volume ; hippocampal volume measures 7,917 mm³, 1.4% above the reference mean. With a Z-score of 0.19 (57.7th percentile), this represents normal volume ; whole brain volume measures 1,072,160 mm³, 3.0% above the reference mean. With a Z-score of 0.36 (64.2th percentile), this represents normal volume ; entorhinal cortex volume measures 3,456 mm³, 6.5% below the reference mean. With a Z-score of -0.51 (30.6th percentile), this represents normal volume ; fusiform gyrus volume measures 20,402 mm³, 10.7% above the reference mean.

  "gpt_diagnosis": "**Reasoning:** All brain volumes (hippocampal, whole brain, entorhinal cortex, fusiform gyrus, middle temporal gyrus) are within normal ranges based on Z-scores and percentiles. Biomarkers (Aβ, T-tau, P-tau, AV45) are normal, and cognitive scores (MMSE 30, MoCA 28) are intact. No significant atrophy or pathological markers are present.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
