With a Z-score of -0.57 (28.3th percentile), this represents normal volume ; hippocampal volume measures 7,808 mm³, 0.0% above the reference mean. With a Z-score of 0.00 (50.0th percentile), this represents normal volume ; whole brain volume measures 1,067,250 mm³, 2.6% above the reference mean. With a Z-score of 0.31 (62.1th percentile), this represents normal volume ; entorhinal cortex volume measures 4,092 mm³, 10.7% above the reference mean. With a Z-score of 0.84 (79.9th percentile), this represents normal volume ; fusiform gyrus volume measures 19,353 mm³, 5.0% above the reference mean. With a Z-score of 0.45 (67.5th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,062 mm³, 2.6% above the reference mean.

  "gpt_diagnosis": "**Reasoning:** All brain volume measures (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) are within normal ranges (Z-scores close to 0, percentiles near 50th). Cognitive scores (MMSE 29, MoCA 30) are intact, and there is no evidence of structural atrophy or cognitive impairment.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
