Tomosynthesis

Digital tomosynthesis is very similar to a CT scan. Essentially, a machine takes many X-ray 'slices' of the breast that can then be pieced back together to create a virtual 3D image of the breast.

Despite recent claims, there is no 3D imaging yet available. Tomosynthesis (aka “tomo”) is about "2.5D" looking at the breast in a 270 degree arc but not 360 degrees. Tomo requires about 8 films and does require compression. It does give a better look at the markedly dense breast. It should not become the "routine screening" for all women. At UMass Memorial, we have been awarded a federal grant along with four other centers in the United States to build and pilot CT scanning for the breast. Our initial work with a home built unit and mastectomy specimens was highly successful leading to the grant award. CT scanning is truly 3D with 360 degree views without compression, faster times and more views. Radiation exposure should be equivalent to Tomo. We have raised over $500,000 to build and install our breast CT unit within the year. Again as with tomo, breast CT is not at this time meant for routine screening.
