With a Z-score of -0.29 (38.6th percentile), this represents normal volume ; hippocampal volume measures 7,889 mm³, 1.0% above the reference mean. With a Z-score of 0.14 (55.8th percentile), this represents normal volume ; whole brain volume measures 1,053,970 mm³, 1.3% above the reference mean. With a Z-score of 0.15 (56.2th percentile), this represents normal volume ; entorhinal cortex volume measures 3,461 mm³, 6.3% below the reference mean. With a Z-score of -0.50 (31.0th percentile), this represents normal volume ; fusiform gyrus volume measures 19,774 mm³, 7.3% above the reference mean. With a Z-score of 0.66 (74.6th percentile), this represents normal volume ; middle temporal gyrus volume measures 20,866 mm³, 1.6% 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. Cognitive scores (MMSE, MoCA) are perfect, and biomarkers (Aβ, T-tau, P-tau, AV45) are normal. No evidence of structural or biochemical abnormalities.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
