Digital mammography uses less radiation

Radiation exposure from digital mammography appears to be much lower than conventional film mammography.

The latest digital mammographic imaging screening trial examined data from about 5,000 women. Researchers say the radiation dose from digital imaging was about 22-percent lower, on average, than film mammography.

Both methods are similar -- but digital mammography collects x-ray images on a computer, while conventional mammograms are captured and stored on film.

The study is published in the February 2010 issue of the American Journal of Roentgenology.
