Abstract
Contrast-enhanced breast MRI is a standard evidence-based component of supplemental screening in conjunction with mammography for higher-risk populations because of its high sensitivity for detecting breast cancer; the use of breast MRI for screening in high-risk populations is recommended in multiple national and international guidelines. The current MRI exam, however, is expensive relative to other screening technologies such as mammography, and relatively more time-intensive. Recent investigations have focused on techniques that have the potential for improving efficiency of the breast MRI exam, decreasing acquisition and reading times, without impacting diagnostic accuracy. The purpose of this article is therefore to provide an overview of current MRI guidelines for screening for breast cancer and to discuss evolving technological approaches to breast MRI, in particular abbreviated and ultrafast MRI protocols, as well as MRI protocols without contrast that have the potential to improve MRI screening. Level of Evidence: 5 Technical Efficacy Stage: 2 J. Magn. Reson. Imaging 2019;49:1212-1221.
