With a Z-score of -0.35 (36.4th percentile), this represents normal volume ; hippocampal volume measures 6,702 mm³, 11.3% below the reference mean. With a Z-score of -1.11 (13.4th percentile), this represents mild atrophy; whole brain volume measures 1,076,170 mm³, 0.3% below the reference mean. With a Z-score of -0.04 (48.5th percentile), this represents normal volume ; entorhinal cortex volume measures 3,579 mm³, 12.7% below the reference mean. With a Z-score of -0.86 (19.4th percentile), this represents normal volume ; fusiform gyrus volume measures 19,294 mm³, 2.4% above the reference mean. With a Z-score of 0.21 (58.2th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,906 mm³, 2.7% above the reference mean.

  "gpt_diagnosis": "**Reasoning:** The hippocampal volume shows mild atrophy (Z-score -1.11, 13.4th percentile), while other brain regions are within normal ranges. Cognitive scores (MMSE 29, MoCA 26) are borderline normal (MoCA slightly below typical cutoff of 26/30 for MCI), but the presence of an APOE4 allele and hippocampal atrophy raises concern for early neurodegenerative changes.  \n\n**Diagnosis:** **Mild Cognitive Impairment (MCI)**  \n**Confidence:** **Medium** (Cognitive scores are near-normal, but hippocampal atrophy and APOE4 status suggest early pathology; clinical correlation with subjective complaints would strengthen confidence.)",
