With a Z-score of -0.72 (23.7th percentile), this represents normal volume ; hippocampal volume measures 6,632 mm³, 4.8% below the reference mean. With a Z-score of -0.42 (33.8th percentile), this represents normal volume ; whole brain volume measures 962,377 mm³, 6.5% below the reference mean. With a Z-score of -0.85 (19.8th percentile), this represents normal volume ; entorhinal cortex volume measures 3,010 mm³, 24.2% below the reference mean. With a Z-score of -1.58 (5.7th percentile), this represents moderate atrophy; fusiform gyrus volume measures 16,795 mm³, 7.0% below the reference mean. With a Z-score of -0.61 (27.1th percentile), this represents normal volume ; middle temporal gyrus volume measures 17,246 mm³, 14.5% below the reference mean. With a Z-score of -1.30 (9.7th percentile), this represents mild atrophy. ",

  "gpt_diagnosis": "Reasoning: The entorhinal cortex shows moderate atrophy (Z-score -1.58, 5.7th percentile), and the middle temporal gyrus shows mild atrophy (Z-score -1.30, 9.7th percentile), which are early markers of Alzheimer's pathology. However, hippocampal and whole brain volumes are within normal limits, and cognitive scores (MMSE 26, MoCA 22) are borderline but not definitively impaired.  \nDiagnosis: MCI (Mild Cognitive Impairment)  \nConfidence:",
