What other breast imaging techniques might be useful for breast cancer screening?
In addition to mammography, ultrasound and magnetic resonance imaging (MRI) are both sometimes used to screen for breast cancer. ACRIN is currently conducting another trial of breast cancer screening, which compares ultrasound vs. mammography in high- risk women. MRI has shown promise for women at high-risk for breast cancer. DMIST did not study either of these other technologies. In fact, women who participated in DMIST were not permitted to participate in other screening trials during the one year immediately before and after their entry into DMIST. There are no multicenter clinical trials investigating the use of either MRI or ultrasound in place of mammography as screening tools for breast cancer for the general population of women over age 40.
