What is Tomosynthesis and how is this different to a 2D mammogram?

2D mammograms are the regular standard procedures. Simply put it means that the breast image is obtained from top to bottom or from side to side. However, there have been advances in breast imaging and early detection of breast cancer has been improved by 40% by Tomosynthesis or 3D Digital Breast Imaging (DGB) This is fast becoming the gold standard for imaging breast tissue. For women with dense tissue breast, this form of imaging has undoubtably improved the peace of mind for both the Radiologist and patient. Tomosynthesis or 3D technology is performed on the standard mammogram machine, allowing for a layered or sliced breast tissue acquisition of images. The Radiologist is then able to view these layers one by one. Not only does this improve the overall result, but also allows for overlaying tissue folds to be fully visualised.

The advantages of Tomosynthesis include:

• The technology is more sensitive with detection of breast cancer. • Fewer recalls for patients especially regarding further biopsies. • Potential less compressing or 'squashing' of the breast thereby reducing the discomfort associated with having a mammogram.
