With a Z-score of -0.76 (22.3th percentile), this represents normal volume ; hippocampal volume measures 7,462 mm³, 2.9% below the reference mean. With a Z-score of -0.32 (37.3th percentile), this represents normal volume ; whole brain volume measures 969,957 mm³, 5.8% below the reference mean. With a Z-score of -0.72 (23.7th percentile), this represents normal volume ; entorhinal cortex volume measures 3,816 mm³, 2.0% below the reference mean. With a Z-score of -0.15 (43.9th percentile), this represents normal volume ; fusiform gyrus volume measures 18,982 mm³, 4.2% 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 (MMSE 30, MoCA 24) shows no significant impairment, and biomarkers (T-tau, P-tau, AV45) are normal. The slightly lower MoCA score may reflect mild non-specific cognitive fluctuations but does not meet MCI criteria.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
