MRI-guided breast interventions.

The use of breast magnetic resonance imaging (MRI) in the diagnosis, staging, and management of breast cancer is rapidly increasing. MRI has the ability to detect malignancy that is occult to physical exam, ultrasound, and mammography. These qualities necessitate methods for MRI-guided tissue sampling.

Screening MRI for women at high risk for breast cancer.

Recognition of the limitations of mammography in screening women at high risk for breast cancer stimulated clinical trials to evaluate magnetic resonance imaging (MRI) as an adjunct to mammography. Based on the results of these trials, there is increased interest in offering screening MRI to high-risk women after discussion of the potential benefits and risks. The benefits include increased cancer detection with MRI and significantly more cancers detected prior to nodal metastases.
