With a Z-score of -0.60 (27.5th percentile), this represents normal volume ; hippocampal volume measures 7,976 mm³, 3.8% above the reference mean. With a Z-score of 0.43 (66.5th percentile), this represents normal volume ; whole brain volume measures 1,035,480 mm³, 0.6% above the reference mean. With a Z-score of 0.08 (53.0th percentile), this represents normal volume ; entorhinal cortex volume measures 3,637 mm³, 6.6% below the reference mean. With a Z-score of -0.51 (30.5th percentile), this represents normal volume ; fusiform gyrus volume measures 17,919 mm³, 1.6% below the reference mean. With a Z-score of -0.18 (42.9th percentile), this represents normal volume ; middle temporal gyrus volume measures 20,241 mm³, 1.4% below the reference mean.

  "gpt_diagnosis": "Reasoning: All brain volume measures (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, middle temporal gyrus) fall within normal ranges (Z-scores between -0.60 and 0.43). Cognitive scores (MMSE 29, MoCA 27) are within normal limits, and amyloid PET (AV45) is normal. No significant atrophy or biomarker evidence of Alzheimer’s pathology.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
