“A computer is as good as a second pair of eyes for helping a radiologist spot breast cancer on a mammogram, one of the largest and most rigorous tests of computer-aided detection found. “
Like spell-checkers looking for mistakes, the computers flag suspicious areas on X-rays for a closer look by a radiologist. Mammograms are used to screen women for early signs of breast cancer but the tests aren’t perfect. In the U.S., the X-rays are read by a single radiologist and cancers are sometimes missed.”
Computed Aided Detection or CAD has been around for quite some time but it has been used (if adopted at all) more for a second (or third) opinion, never really used as the primary screener due to the ‘miss rate’
Now, a new study conducted by British researchers are reporting results from a randomized study of 31,000 women to compare if a single expert aided by a computer could do as well as two pairs of eyes. Mammograms in Britain are routinely checked by two radiologists or technicians – which is thought to be better than a single review).
The results? – they found that computer-aided detection spotted nearly the same number of cancers, 198 out of 227, compared to 199 for the two readers. Not too bad eh.
