Digital Mammographic Imaging Screening Trial

The Digital Mammographic Imaging Screening Trial (DMIST) is a multi-institutional research study, beginning in 2001, on the efficacy for screening of full-field digital mammography (FFDM) compared to conventional film-screen mammography that was sponsored by the U.S. National Cancer Institute and performed by the American College of Radiology Imaging Network (ACRIN).^[1] The findings^[2][3] that FFDM was not inferior to the existing technology, and potentially superior in younger women with dense breasts, has led to a rapid proliferation of digital systems in the US.^{[citation needed]} On the other hand, women with dense breasts receive two to three times the amount of radiation during their imaging as dense breasts absorb more X-ray because of the density (difficulty of the X-ray to penetrate dense tissue).^{[citation needed]}
