With a Z-score of 0.17 (56.6th percentile), this represents normal volume ; hippocampal volume measures 5,877 mm³, 15.7% below the reference mean. With a Z-score of -1.35 (8.8th percentile), this represents mild atrophy; whole brain volume measures 1,092,340 mm³, 6.1% above the reference mean. With a Z-score of 0.80 (78.9th percentile), this represents normal volume ; entorhinal cortex volume measures 2,965 mm³, 25.3% below the reference mean. With a Z-score of -1.66 (4.9th percentile), this represents moderate atrophy; fusiform gyrus volume measures 17,163 mm³, 5.0% below the reference mean. With a Z-score of -0.43 (33.3th percentile), this represents normal volume ; middle temporal gyrus volume measures 20,108 mm³, 0.3% below the reference mean.

  "gpt_diagnosis": "**Reasoning:** The patient shows mild hippocampal atrophy (Z-score -1.35) and moderate entorhinal cortex atrophy (Z-score -1.66), both key regions in Alzheimer's pathology. Cognitive testing (MMSE 24, MoCA 19) indicates mild cognitive impairment, and the absence of APOE4 does not rule out AD.  \n\n**Diagnosis:** **Mild Cognitive Impairment (MCI)** (likely due to underlying Alzheimer’s pathology given atrophy patterns).  \n\n**Confidence:** **Medium** (clinical correlation needed to exclude other causes, but imaging and cognitive scores strongly suggest MCI).",
