Breast MR imaging at 3T

Abstract

For breast MR imaging, a high spatial resolution is important to resolve morphologic and architectural details of even small tumors. At the same time, fast imaging is required to account for the transient enhancement of breast cancers. This is the "temporal versus spatial dilemma" that current breast MR imaging protocols face. This article provides a short introduction to the clinical use of breast MR imaging, presents the different concepts that exist for breast MR imaging in general, and explains the advantages and disadvantages of the respective approaches. The specific high-field-induced physical changes and their effects on breast imaging are explained. A short overview is given on the current level of evidence regarding breast MR imaging at higher magnetic fields.
