With a Z-score of -0.23 (41.0th percentile), this represents normal volume ; whole brain volume measures 1,089,690 mm³, 1.0% above the reference mean. With a Z-score of 0.12 (54.9th percentile), this represents normal volume ; entorhinal cortex volume measures 4,242 mm³, 3.4% above the reference mean. With a Z-score of 0.23 (59.2th percentile), this represents normal volume ; fusiform gyrus volume measures 21,178 mm³, 12.4% above the reference mean. With a Z-score of 1.06 (85.5th percentile), this represents mild enlargement; middle temporal gyrus volume measures 22,595 mm³, 5.9% above the reference mean. With a Z-score of 0.53 (70.2th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: All brain volume measures (hippocampus, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) are within normal ranges or mildly enlarged, with no significant atrophy. Cognitive scores (MMSE 30, MoCA 29) are intact, and there is no APOE4 genetic risk factor.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
