The recent development of new imaging procedures has lead the radiologists to assessing the diagnostic efficacy of the available examination techniques in order to reduce medical care costs. In cooperation with epidemiologists and statisticians, several methods of statistic analysis of the diagnostic efficacy of the procedures such as sensitivity and specificity evaluation, ROC analysis, disease prevalence, predictive value of tests, etc... have been developed. Benefit-cost and cost-efficiency analyses have also been performed, with a view to improving the quality of long-term medical care for the patient at a lower cost both for himself and the society.
近期新型成像程序的发展促使放射科医生评估现有检查技术的诊断效能，以降低医疗成本。放射科医生与流行病学家和统计学家合作，开发了几种用于分析诊断效能的统计方法，如敏感度和特异度评估、受试者工作特征（ROC）分析、疾病患病率、检验预测值等。还进行了效益成本分析和成本效益分析，旨在以较低的成本为患者及其所在社会提高长期医疗护理质量。
