With a Z-score of -0.94 (17.3th percentile), this represents normal volume ; hippocampal volume measures 7,615 mm³, 7.0% above the reference mean. With a Z-score of 0.65 (74.1th percentile), this represents normal volume ; whole brain volume measures 981,764 mm³, 0.7% above the reference mean. With a Z-score of 0.09 (53.7th percentile), this represents normal volume ; entorhinal cortex volume measures 3,451 mm³, 6.0% below the reference mean. With a Z-score of -0.37 (35.5th percentile), this represents normal volume ; fusiform gyrus volume measures 17,584 mm³, 3.4% above the reference mean. With a Z-score of 0.31 (62.0th percentile), this represents normal volume ; middle temporal gyrus volume measures 20,702 mm³, 8.0% above the reference mean.

  "gpt_diagnosis": "Reasoning: All brain volumes (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, middle temporal gyrus) are within normal ranges based on Z-scores and percentiles. Cognitive scores (MMSE 30, MoCA 26) are normal for age, and amyloid PET (AV45) is normal. No APOE4 risk allele is present.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
