Computer-aided detection, or CAD, was developed to help radiologists pick up more cancers. Approved a decade ago, these computer programs are now used for about a third of the nation's mammograms. But the value and accuracy of the technology has continued to be debated.
Now, British researchers are reporting results from a randomized study of 31,000 women. Mammograms in Britain are routinely checked by two radiologists or technicians, which is thought to be better than a single review. Researchers wanted to know if a single expert aided by a computer could do as well as two pairs of eyes.
