Researchers assessing the impact of revised guidelines for screening mammography issued by the U.S. Preventive Services Task Force (USPSTF) found evidence that the new recommendations may lead to missed cancers and a decline in screening, according to two studies presented at the annual meeting of the Radiological Society of North America (RSNA).

There were several evident trends on the show floor at RSNA 2012, including interest in software fueled by Stage 1 and 2 meaningful use requirements, new mammography solutions and innovations in imaging hardware.

The radiation dose to areas of the body near the breast during mammography is negligible, or very low, and does not result in an increased risk of cancer, according to a study presented at the annual meeting of the Radiological Society of North America (RSNA). The results suggest that the use of thyroid shields during mammography is unnecessary.
