With a Z-score of 0.52 (69.8th percentile), this represents normal volume ; hippocampal volume measures 6,557 mm³, 7.8% below the reference mean. With a Z-score of -0.72 (23.6th percentile), this represents normal volume ; whole brain volume measures 1,022,050 mm³, 4.9% above the reference mean. With a Z-score of 0.61 (73.0th percentile), this represents normal volume ; entorhinal cortex volume measures 3,119 mm³, 15.1% below the reference mean. With a Z-score of -0.93 (17.7th percentile), this represents normal volume ; fusiform gyrus volume measures 17,963 mm³, 5.6% above the reference mean. With a Z-score of 0.51 (69.4th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,341 mm³, 11.3% above the reference mean. With a Z-score of 0.98 (83.7th percentile), this represents normal volume . ",

  "gpt_diagnosis": "**Reasoning:** The brain volume measurements, including hippocampal and entorhinal cortex volumes, are within normal ranges despite slight deviations from the reference mean. Cognitive scores (MMSE 30, MoCA 28) are intact, and there is no APOE4 genetic risk factor.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
