With a Z-score of -0.74 (22.8th percentile), this represents normal volume ; hippocampal volume measures 6,540 mm³, 8.1% below the reference mean. With a Z-score of -0.74 (22.9th percentile), this represents normal volume ; whole brain volume measures 973,435 mm³, 0.1% below the reference mean. With a Z-score of -0.02 (49.4th percentile), this represents normal volume ; entorhinal cortex volume measures 2,814 mm³, 23.4% below the reference mean. With a Z-score of -1.44 (7.6th percentile), this represents mild atrophy; fusiform gyrus volume measures 15,998 mm³, 6.0% below the reference mean. With a Z-score of -0.54 (29.4th percentile), this represents normal volume ; middle temporal gyrus volume measures 17,474 mm³, 8.8% below the reference mean.

  "gpt_diagnosis": "Reasoning: The entorhinal cortex shows mild atrophy (Z-score -1.44, 7.6th percentile), which is notable given its role in memory and early Alzheimer's pathology. However, other brain volumes (hippocampus, whole brain, fusiform gyrus, middle temporal gyrus) are within normal ranges. The MMSE (26) is borderline, while the MoCA (19) suggests mild cognitive impairment, supported by APOE4 positivity.  \n\nDiagnosis: **MCI**  \nConfidence: **Medium** (Structural changes are mild, but cognitive scores and genetic risk suggest early decline.)",
