DESCRIPTION: The study will use mammography films randomly sampled from a typical screening population with disease status determined before sampling by biopsy or long-term follow up and subsequent negative mammography exam. These films will be interpreted by radiologists from randomly sampled facilities having a mammography unit accredited by the American College of Radiology. Regression models for ROC curves will be used to relate variability in interpretation and diagnostic accuracy as functions of radiologist and patient characteristics. The influence of comparison exams, geographic variability and intra-reader variability on mammogram interpretation will be investigated.

描述：该研究将使用从一个随机取样的乳房X线摄影膜 采样前确定的典型筛查人群具有疾病状态 通过活检或长期随访以及随后的阴性乳房摄影检查。 这些电影将由放射科医生从随机抽样解释 拥有乳房X线摄影单元的设施已获得美国美国学院的认可 放射学。 ROC曲线的回归模型将用于关联 解释和诊断准确性的可变性作为功能 放射科医生和患者特征。 比较考试的影响， 乳房X线照片上的地理变异性和内部阅读器可变性 解释将被调查。
