Changes in technology are altering the role of magnetic resonance imaging (MRI) in breast imaging. MRI continues to show improvement in the detection and diagnosis of breast cancer, even in its earliest stages. It is especially beneficial for imaging lesions that are occult on other modalities. To better understand the role of MRI in conventional breast imaging and as a modality for guiding biopsies this article will provide a review of basic MR breast imaging techniques, an overview for technologists of MRI-guided stereotactic breast biopsy procedures, and highlights of the pros and cons of MRI breast biopsy guidance as an alternative to surgical biopsy. The role of the MRI technologist, various safety considerations, and technical developments are also discussed.
After reading this article, the participant should be able to:
- Discuss magnetic resonance imaging (MRI) techniques for the breast.
- Examine MRI-guided stereotactic breast biopsy procedures.
- Evaluate the benefits and disadvantages of MRI as a modality for guiding breast biopsies.
- Describe the role of the MRI technologist and important safety considerations for the use of MRI.
