Role of MRI in breast cancer management.

In breast cancer, different situations call for different imaging tests. Mammography is the test of choice for screening women with no signs or symptoms of breast cancer. For diagnosis, tailored mammographic views and ultrasonography are the norm. Magnetic resonance imaging (MRI) is highly sensitive for cancer staging, problem-solving, posttreatment surveillance, and other indications. It can detect primary breast cancers and additional foci of cancer that are occult to standard imaging. Continued improvements in technology and studies to assess outcomes will help to better define MRI's role in breast cancer.
