But, DMIST was not designed to compare any difference in mortality among women who had different imaging types--so it can't answer whether digital mammography could save more lives than film.
The DMIST trial indicated that screening all women with digital mammograms was not cost-effective, because digital costs more and doesn't improve health outcomes when used so broadly.

It's been a decade since the pivotal DMIST
study determined that digital mammography delivers greater breast cancer detection accuracy than film-screen mammography in women under age 50 and those with radiographically dense breasts.

The recent Digital Mammography Imaging Screening Test (DMIST
) study released in September highlights the comparative benefits of film-based and digital mammography.
According to the American College of Radiology Imaging Network (ACRIN) and the results of the Digital Mammography Imaging Screening Trial (DMIST), which was conducted between July 2001 and November 2003, overall digital and filmscreen mammography are comparable methodologies.
As the DMIST results have proven, the benefits of digital mammography over filmscreen are limited to specific groups of women.
The Digital Mammographic Imaging Screening Trial (DMIST) was designed to compare the sensitivity of digital mammography with that of film-based mammography for breast cancer detection.
"The subgroups that were mentioned actually represent a majority of the screening population: 65% of the 49,000+ women who participated in DMIST fell into at least one of those categories.
DMIST showed that 40% of them do have dense breasts.
