Wolfe has described different cancer risks associated with a classification of four patterns of the breast parenchyma on mammography, but there is however little information available on the ability of radiologists to agree on the classification of the different patterns. We have assessed inter-rater agreement on the assignment of films to one of the four mammographic patterns described by Wolfe. One hundred xeromammograms were selected, copied and distributed to 10 radiologists who were experts in mammography. Films were classified according to the presence or absence of several radiological signs, according to diagnosis and recommendation, and according to mammographic pattern. Agreement was assessed after correction for agreement expected by chance, using the Kappa statistic. In general, high levels of agreement were found for the classification of mammographic pattern. Agreement on the classification of mammographic pattern was substantially greater than agreement for any other feature of mammographic interpretation, including diagnosis and recommendation.
沃尔夫描述了与乳腺钼靶检查中乳腺实质的四种模式分类相关的不同癌症风险，然而，关于放射科医生对不同模式分类达成一致的能力，几乎没有可用信息。我们评估了在将乳腺钼靶片分配到沃尔夫描述的四种钼靶模式之一时的评分者间一致性。选择了100张干板乳腺造影片，进行复制并分发给10位乳腺钼靶专家。根据几种放射学征象的有无、诊断和建议以及钼靶模式对片子进行分类。使用卡方统计量，在对偶然预期的一致性进行校正后评估一致性。总体而言，在钼靶模式分类方面发现了高度一致性。在钼靶模式分类上的一致性显著高于钼靶解读的任何其他特征（包括诊断和建议）的一致性。
