With a Z-score of 0.22 (58.6th percentile), this represents normal volume ; hippocampal volume measures 7,394 mm³, 2.2% below the reference mean. With a Z-score of -0.21 (41.6th percentile), this represents normal volume ; whole brain volume measures 1,034,170 mm³, 4.2% below the reference mean. With a Z-score of -0.54 (29.3th percentile), this represents normal volume ; entorhinal cortex volume measures 3,645 mm³, 11.1% below the reference mean. With a Z-score of -0.75 (22.6th percentile), this represents normal volume ; fusiform gyrus volume measures 18,668 mm³, 0.9% below the reference mean.

  "gpt_diagnosis": "**Reasoning:** The brain volumes are within normal ranges, with only mild deviations from the reference mean (all Z-scores within normal limits). Biomarkers (Aβ, T-tau, P-tau, AV45) are normal, but the MoCA score (22/30) suggests mild cognitive impairment despite a normal MMSE (29/30).  \n**Diagnosis:** **MCI** (Mild Cognitive Impairment)  \n**Confidence:** **Medium** (due to the discrepancy between MMSE and MoCA, but normal biomarkers and imaging suggest early-stage cognitive changes rather than dementia)",
