  "img_finding": "Image findings: whole brain volume measures 1,169,420 mm³, 8.3% above the reference mean. With a Z-score of 1.08 (86.1th percentile), this represents mild enlargement; entorhinal cortex volume measures 4,606 mm³, 12.3% above the reference mean. With a Z-score of 0.84 (79.8th percentile), this represents normal volume ; fusiform gyrus volume measures 18,733 mm³, 0.6% below the reference mean. With a Z-score of -0.05 (48.1th percentile), this represents normal volume ; middle temporal gyrus volume measures 23,234 mm³, 8.9% above the reference mean. With a Z-score of 0.80 (78.8th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volumes are largely within or above the reference range, with no significant atrophy in key regions like the entorhinal cortex or fusiform gyrus. The MMSE score is normal (28/30), but the MoCA score (22/30) suggests mild cognitive impairment, though APOE4-negative status and normal AV45 (amyloid PET) reduce the likelihood of Alzheimer's pathology.  \nDiagnosis: **MCI**  \nConfidence: **Medium** (MoCA suggests impairment, but structural and biomarker data do not strongly support dementia or neurodegeneration).",
