Magnetic resonance imaging for primary breast cancer management: current role and new applications.

Techniques for magnetic resonance (MR) imaging of the breast have been evolving over the past decade. The opportunities for integration of MR imaging into clinical breast cancer management and clinical research are increasing. In this paper, we will review the principles behind the creation of standard and MR images and use this as a platform to evaluate clinical studies and indications for the use and study of MR. In particular, we will focus on those areas where MR has the capability of changing care and/or improving our understanding of the biology of breast cancer. In addition, we will address areas where MR is not yet capable of adding value or where MR may lead to unnecessary procedures.
