  "img_finding": "Image findings: whole brain volume measures 1,193,120 mm³, 22.4% above the reference mean. With a Z-score of 2.82 (99.8th percentile), this represents significant enlargement; entorhinal cortex volume measures 4,035 mm³, 9.9% above the reference mean. With a Z-score of 0.61 (72.7th percentile), this represents normal volume ; fusiform gyrus volume measures 21,166 mm³, 24.4% above the reference mean. With a Z-score of 2.22 (98.7th percentile), this represents significant enlargement; middle temporal gyrus volume measures 23,658 mm³, 23.4% above the reference mean. With a Z-score of 2.03 (97.9th percentile), this represents significant enlargement. ",
  "text_data": "Age is 75.9 years. Gender is Female. Education: 17 years. MMSE: 28.0. MoCA: 22.0. Logical Memory: 8.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The brain volumes show significant enlargement in multiple regions (whole brain, fusiform gyrus, middle temporal gyrus) and normal entorhinal cortex volume, which is atypical for Alzheimer's. The MMSE is normal (28/30), but the MoCA (22/30) suggests mild cognitive impairment. No APOE4 alleles reduce Alzheimer's risk.  \nDiagnosis: MCI (Mild Cognitive Impairment)  \nConfidence: Medium (MoCA suggests impairment, but atypical brain volume patterns and lack of APOE4 make Alzheimer's less likely)",
