They have me down for a Digital tomosynthesis a 3-dimensional picture of the breast using X-rays. from Google: Digital tomosynthesis is a new kind of test that's trying to overcome these three big issues. It takes multiple X-ray pictures of each breast from many angles. The breast is positioned the same way it is in a conventional mammogram, but only a little pressure is applied — just enough to keep the breast in a stable position during the procedure. The X-ray tube moves in an arc around the breast while 11 images are taken during a 7-second examination. Then the information is sent to a computer, where it is assembled to produce clear, highly focused 3-dimensional images throughout the breast.
Early results with digital tomosynthesis are promising. Researchers believe that this new breast imaging technique will make breast cancers easier to see in dense breast tissue and will make breast screening more comfortable.
I'll let you know if it's more comfortable or not!
