With a Z-score of -0.59 (27.7th percentile), this represents normal volume ; hippocampal volume measures 7,465 mm³, 2.9% below the reference mean. With a Z-score of -0.32 (37.4th percentile), this represents normal volume ; whole brain volume measures 1,019,470 mm³, 0.9% below the reference mean. With a Z-score of -0.12 (45.3th percentile), this represents normal volume ; entorhinal cortex volume measures 3,769 mm³, 3.2% below the reference mean. With a Z-score of -0.25 (40.3th percentile), this represents normal volume ; fusiform gyrus volume measures 17,337 mm³, 4.8% below the reference mean. With a Z-score of -0.54 (29.5th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,351 mm³, 4.1% above the reference mean.

  "gpt_diagnosis": "Reasoning: All brain volumes (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) are within normal ranges based on Z-scores and percentiles. Cognitive scores (MMSE: 29, MoCA: 30) are also intact, and there is no APOE4 genetic risk factor.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
