Magnetic resonance imaging (MRI) has been demonstrated to be, and recommended as, an efficacious adjunct to mammography for very high-risk, dense-breasted women [5, 6]. It has not been recommended for all dense-breasted women. Three limitations to MRI screening for breast cancer are cost, intravenous injection of gadolinium-containing contrast medium, and lower specificity of MRI compared with mammography [7] with increased false positive callbacks and biopsies.
