With a Z-score of 0.18 (57.3th percentile), this represents normal volume ; hippocampal volume measures 7,191 mm³, 1.1% above the reference mean. With a Z-score of 0.10 (53.9th percentile), this represents normal volume ; whole brain volume measures 988,806 mm³, 1.5% above the reference mean. With a Z-score of 0.18 (57.3th percentile), this represents normal volume ; entorhinal cortex volume measures 3,652 mm³, 0.6% below the reference mean. With a Z-score of -0.03 (48.6th percentile), this represents normal volume ; fusiform gyrus volume measures 19,715 mm³, 15.9% above the reference mean. With a Z-score of 1.45 (92.6th percentile), this represents mild enlargement; middle temporal gyrus volume measures 18,260 mm³, 4.7% below the reference mean.

  "gpt_diagnosis": "Reasoning: All brain volumes (ventricular, hippocampal, whole brain, entorhinal cortex, middle temporal gyrus) are within normal ranges or show only mild variations (fusiform gyrus enlargement). Cognitive scores (MMSE 30, MoCA 27) are normal, and biomarkers (T-tau, P-tau, AV45) are unremarkable. No significant atrophy or pathological changes are present.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
