目的：确定筛查乳房X光检查的解释技能是否与诊断乳房X光检查的解释技能相关。材料和南加州大学机构审查委员会方法：佛罗里达州批准了这项研究，由于图像的回溯使用，这项研究被确定为免除知情同意要求，并在HIPPA要求实施之前进行。共有59名放射科医生每隔一年解释一次X线影像筛查和诊断性能测试集。通过修改乳房成像和报告数据系统记录解释。放射科医生的技能被衡量为放射科医生在他或她的队列中的几个性能测量(即性能测试接收器操作特征曲线面积、性能测试筛查灵敏度、性能测试诊断灵敏度和相关的特异性)中的排名。采用Spearman等级相关统计检验，分析筛查和诊断解释中放射科医师等级之间的相关性。结果：筛查和诊断解释中的放射科医师等级在所有测量中均显著相关(P<；.05)。然而，在调整多次测试后，只有两个测量(即，接收者操作特征曲线面积等级相关性为0.327，灵敏度等级相关性为0.402)仍然显著。分级筛查特异度和分级诊断特异度(0.296)之间的相关性仅在0.05水平上显著。结论：放射科医师在同龄人中的解释能力在筛查和诊断解释之间存在中等程度的相关性。因此，对于一些放射科医生来说，精通一个领域并不能保证精通另一个领域。(C)RSNA，2006年
Purpose: To determine whether skill in the interpretation of screening mammograms is correlated with skill in the interpretation of diagnostic mammograms.Materials and The institutional review board of the University of South Methods: Florida approved this study, This study was determined to be exempt from informed consent requirements because of the retrospective use of images and was conducted before HIPPA requirements were implemented. A total of 59 radiologists interpreted screening and diagnostic performance test sets of marnmograms with a 1-year interval. Interpretations were recorded with modifications of the Breast Imaging and Reporting Data System. Radiologist skill was measured as the radiologist's ranking among his or her cohort in each of several measures of performance (ie, performance test receiver operating characteristic curve area, performance test screening sensitivity, performance test diagnostic sensitivity, and associated specificities). Correlations between radiologist rank in screening and rank in the diagnostic performance test measures were analyzed with the Spearman rank correlation statistical test.Results: Radiologist rank in screening interpretations and in diagnostic interpretations was found to be significantly correlated in all measurements (P < .05). However, only two measurments (ie, receiver operating characteristic curve area rank correlation of 0.327 and sensitivity rank correlation of 0.402) remained significant after adjusting for multiple testing. The correlation between ranked screening specificity and ranked diagnostic specificity (0.296) was significant at only the .05 level.Conclusion: The interpretive performance of radioldgists among their peers is moderately correlated between screening and diagnostic interpretations. Thus, proficiency in one area does not guarantee proficiency in the other area for some radiologists. (c) RSNA, 2006
