With a Z-score of -0.28 (39.0th percentile), this represents normal volume ; hippocampal volume measures 5,795 mm³, 10.8% below the reference mean. With a Z-score of -0.86 (19.4th percentile), this represents normal volume ; whole brain volume measures 931,839 mm³, 0.4% above the reference mean. With a Z-score of 0.05 (51.9th percentile), this represents normal volume ; entorhinal cortex volume measures 2,357 mm³, 31.9% below the reference mean. With a Z-score of -1.72 (4.2th percentile), this represents moderate atrophy; fusiform gyrus volume measures 12,119 mm³, 24.8% below the reference mean. With a Z-score of -1.86 (3.1th percentile), this represents moderate atrophy; middle temporal gyrus volume measures 17,380 mm³, 3.6% below the reference mean.

  "gpt_diagnosis": "**Reasoning:** The entorhinal cortex and fusiform gyrus show moderate atrophy (Z-scores -1.72 and -1.86, respectively), which are early markers of Alzheimer's pathology. However, hippocampal and whole-brain volumes are within normal ranges, and the MMSE score of 27 is intact. No APOE4 alleles further reduce genetic risk.  \n\n**Diagnosis:** **Mild Cognitive Impairment (MCI)**  \n**Confidence:** **Medium** (Atrophy in key regions suggests early neurodegeneration, but preserved cognition and normal hippocampal volume make dementia less likely.)",
