Narrator: This is Science Today. Researchers at the University of California , Davis Medical Center are working on new technology that may prove to be equal to or better than mammography at detecting breast cancer. It's a new adaptation of computer tomography. Dr. Karen Lindfors, a professor of radiology, says the CT scan may be far less painful for women, too.
Lindfors: I think it will be very welcome by most women because most women find compression uncomfortable and we don't use any compress for this exam.
Narrator: Currently, when radiologists look at mammograms, they're seeing two-dimensional images. The new test lets them see in 3-D.
Lindfors: When we do our CT scans, we are looking at very thin slices of the breast, so we've eliminated all that background. And therefore, we can pick up these abnormalities, perhaps with greater accuracy.
Narrator: There are still years of research necessary before it becomes available to the public. For Science Today, I'm Larissa Branin.
