公开/Public

盲法:

1. CT图像质量的主观评价由两位具有5年以上腹部CT阅片经验的放射科医生采用双盲法分别对所有图像进行评价 2. 辐射剂量指标的测量由一位高年级研究生独立完成,测量者对于受试者信息及分组情况完全不知情

Blinding:

1. All images are blinded analyzed by two experienced radiologists with more than five-year experience about abdomen CT. 2. Radiation dose indexes are measured by a upper-level graduate student independently, who were blind to the subjects’ clinical finding and group information.
