CAD e mamografia: por que usar esta ferramenta?

mammography is the best method for early detection of breast cancer. nevertheless, approximately 10% to 30% of breast lesions are missed at screening due to limitations of human observers. computer-aided detection (cad) is a relatively new technology that has been implemented in some mammography services to allow a double reading of mammograms. clinical studies have demonstrated that cad increases the sensitivity by up to 21% in the detection of breast cancer by radiologists. a cad system is useful in situations where there is a high interobserver variability, lack of trained observers, or impossibility to perform the double reading with two or more radiologists. the objective of the present review is based on the need to get the medical community acquainted with this tool as an auxiliary, quantitative and non-operator-dependent method, to improve the diagnosis of breast cancer.
