Utilization of breast cancer screening with magnetic resonance imaging in community practice

摘要

Abstract Background Breast cancer screening with magnetic resonance imaging (MRI) may be a useful adjunct to screening mammography in high-risk women, but MRI uptake may be increasing rapidly among low- and average-risk women for whom benefits are unestablished. Comparatively little is known about use of screening MRI in community practice. Objective To assess relative utilization of MRI among women who do and do not meet professional society guidelines for supplemental screening, and describe utilization according to breast cancer risk indications. Design Prospective cohort study conducted between 2007 and 2014. Participants In five regional imaging registries participating in the Breast Cancer Surveillance Consortium (BCSC), 348,955 women received a screening mammogram, of whom 1499 underwent screening MRI. Main measures Lifetime breast cancer risk ( Key results Among women with Conclusion Utilization of screening MRI in community settings is not consistent with current professional guidelines and the goal of delivery of high-value care.
