Mammography remains the primary modality for breast cancer diagnosis. Other imaging studies, most commonly ultrasonography and magnetic resonance imaging, are also used to characterize breast lesions, stage breast cancer, and aid in surgical planning. Although mammography is the only screening examination demonstrated to decrease breast cancer mortality in the general population, other imaging studies have been shown to be beneficial for screening high-risk patients. In the future, new technologies may also improve the sensitivity and specificity of breast cancer screening and detection.
