Strengths of tomosynthesis could hinder its adoption

December 3, 2008 DiagnosticImaging.com. Strengths of tomosynthesis could hinder its adoption By Rebekah Moan While radiologists herald breast tomosynthesis as the hope for the future of breast imaging, several barriers hinder its widespread use. Its very ability to detect benign lesions dilutes the value of such detection, according to a keynote speech at the RSNA meeting. Radiologists hope breast tomosynthesis will improve sensitivity in detection of breast cancer by removing overlapping… Continue
