iCAD Comments on Recent CAD, Mammography Study

iCAD, Inc. (Nashua, NH, USA), an industry-leading provider of computer-aided detection (CAD) systems for the early identification of cancer, commented on a study published in the April 5, 2007, issue of the New England Journal of Medicine (NEJM) entitled, "Influence of Computer-Aided Detection on Performance of Screening.”

CAD uses advanced algorithms to identify areas of interest on a mammography film, acting as a "second set of eyes” for the radiologist. The researchers of the recent NEJM study concluded that the use of CAD is "associated with reduced accuracy of interpretation of screening mammograms. The increased rate of biopsy with the use of computer-aided detection is not clearly associated with improved detection of invasive breast cancer.”

In response to that article, iCAD stated that numerous peer-reviewed published studies confirm that CAD technology finds more tumors earlier, a point that remains undisputed. The company noted that the authors of this study assessed results from the use of older versions of CAD software released to the market five to nine years ago. Over the last several years, there have been considerable developments made to CAD technology, and more specifically, in its sensitivity to finding cancer and reducing false-positives. Additionally in that time, more than 25 published studies evaluating CAD technology have demonstrated the benefits of the technology in improving the detection of cancer, according to iCAD.
