  "img_finding": "Image findings: ventricular volume measures 32,655 mm³, 8.8% above the reference mean. With a Z-score of 0.21 (58.2th percentile), this represents normal volume ; hippocampal volume measures 8,997 mm³, 12.1% above the reference mean. With a Z-score of 1.21 (88.6th percentile), this represents mild enlargement; whole brain volume measures 1,230,390 mm³, 8.4% above the reference mean. With a Z-score of 1.20 (88.4th percentile), this represents mild enlargement; entorhinal cortex volume measures 3,738 mm³, 12.3% below the reference mean. With a Z-score of -0.85 (19.7th percentile), this represents normal volume ; fusiform gyrus volume measures 24,062 mm³, 20.9% above the reference mean. With a Z-score of 1.73 (95.9th percentile), this represents moderate enlargement; middle temporal gyrus volume measures 24,853 mm³, 10.9% above the reference mean. With a Z-score of 0.90 (81.5th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain imaging shows normal to mildly enlarged volumes in most regions, except for the entorhinal cortex, which is slightly below the reference mean but still within normal range. The MoCA score of 23 suggests mild cognitive impairment, while the MMSE of 30 is normal, indicating a possible discrepancy. The presence of two APOE4 alleles increases Alzheimer's risk, but current imaging does not show significant atrophy.  \nDiagnosis: MCI  \nConfidence: Medium",
