Low-Dose 3D Mammography
(Digital Breast Tomosynthesis)
with C-View 2D Imaging Software
Low-Dose 3D Mammography, also known as Digital Breast Tomosynthesis, produces images that appear to be three dimensional. The camera moves over the breast in an arc taking pictures in slices that can be viewed one millimeter at a time so abnormal tissue may be seen more clearly.
The additional C-View 2D imaging software converts the images from 3D to 2D for a composite picture, so patients do not need a second 2D exam – which means half the amount of radiation as well as half the time spent in compression compared to Tomosynthesis exams that do not have C-View imaging
During the exam, the breast is compressed between two plates. Good compression helps by spreading the tissue out to obtain a clear picture and to pick up tiny, minute areas that could possibly be early signs of cancer. Compression also reduces radiation exposure to the breast.
Mammography is still considered the gold standard for early breast cancer detection and Tomosynthesis is essentially an improved mammogram. The decline in breast cancer mortality has been attributed, in large part, to the regular use of screening mammography.
However, Mammography alone, even Tomosynthesis, is not the only imaging modality we need to find cancer. We may recommend supplemental imaging when an exam is inconclusive due to dense breast tissue or other factors.
