With a Z-score of 0.18 (57.2th percentile), this represents normal volume ; whole brain volume measures 1,052,460 mm³, 2.3% above the reference mean. With a Z-score of 0.30 (61.7th percentile), this represents normal volume ; entorhinal cortex volume measures 3,779 mm³, 4.8% below the reference mean. With a Z-score of -0.31 (37.7th percentile), this represents normal volume ; fusiform gyrus volume measures 15,941 mm³, 11.8% below the reference mean. With a Z-score of -1.02 (15.4th percentile), this represents mild atrophy; middle temporal gyrus volume measures 21,876 mm³, 8.4% above the reference mean. With a Z-score of 0.76 (77.6th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The hippocampal and whole brain volumes are within normal ranges, but the fusiform gyrus shows mild atrophy. Cognitive scores (MMSE 25, MoCA 23) are slightly below typical thresholds for normal cognition but do not meet criteria for dementia. No APOE4 alleles reduce genetic risk.  \nDiagnosis: Mild Cognitive Impairment (MCI)  \nConfidence: Medium",
