With a Z-score of 0.22 (58.7th percentile), this represents normal volume ; whole brain volume measures 1,065,990 mm³, 3.6% above the reference mean. With a Z-score of 0.47 (68.0th percentile), this represents normal volume ; entorhinal cortex volume measures 4,357 mm³, 9.8% above the reference mean. With a Z-score of 0.64 (73.9th percentile), this represents normal volume ; fusiform gyrus volume measures 21,649 mm³, 19.8% above the reference mean. With a Z-score of 1.72 (95.7th percentile), this represents moderate enlargement; middle temporal gyrus volume measures 22,332 mm³, 10.7% above the reference mean. With a Z-score of 0.96 (83.1th percentile), this represents normal volume . ",

  "gpt_diagnosis": "**Reasoning:** All brain volume measures (hippocampus, whole brain, entorhinal cortex, fusiform gyrus, middle temporal gyrus) are within or above normal ranges, with no significant atrophy. Biomarkers (Aβ, T-tau, P-tau) are normal, and cognitive performance (MMSE 29/30) is intact. No genetic risk (APOE4 negative).  \n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
