With a Z-score of -0.23 (40.8th percentile), this represents normal volume ; hippocampal volume measures 7,638 mm³, 4.9% below the reference mean. With a Z-score of -0.48 (31.4th percentile), this represents normal volume ; whole brain volume measures 1,098,670 mm³, 3.2% below the reference mean. With a Z-score of -0.45 (32.7th percentile), this represents normal volume ; entorhinal cortex volume measures 4,331 mm³, 1.6% above the reference mean. With a Z-score of 0.11 (54.4th percentile), this represents normal volume ; fusiform gyrus volume measures 20,823 mm³, 4.6% above the reference mean. With a Z-score of 0.38 (64.9th percentile), this represents normal volume ; middle temporal gyrus volume measures 24,859 mm³, 10.9% above the reference mean. With a Z-score of 0.90 (81.6th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volume measures (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) are all within normal ranges, with Z-scores close to or slightly below the mean. The MMSE score of 29 is within the normal range, but the MoCA score of 25 is borderline, suggesting possible mild cognitive impairment (MCI). The AV45 scan showing mild reduction could indicate early amyloid deposition, but the structural imaging does not yet show significant atrophy.  \nDiagnosis: MCI  \nConfidence: Medium",
