Answer

CAD or computer aided detection is a computer-based technology that helps the radiologist in identifying suspicious areas while reading a digitalized mammogram. It was approved by the FDA in 1998. No randomized trials have been performed to assess its effect on breast cancer mortality. A recent meta-analysis showed a small statistically insignificant increase in cancer detection rate, but this was associated with a higher recall rate and more false-positive readings. [15]
