What to expect on the day A 3D mammography (Tomosynthesis) exam is very similar to a traditional mammogram. Just as with a 2D mammogram, the technologist will position and compress your breast to take the images. During the 3D mammography (Tomosynthesis) part of the exam, the x-ray arm will sweep in a small arc over your breast to make highly detailed 3D images. Our radiologist is then able to view your 3D breast images in many different ways with increased information and accuracy. There is no additional compression (pressure) required with 3D mammography, and it only takes a few seconds longer. The radiologist will review your images and provide a detailed report to your doctor. 1. American Cancer Society, Facts and Figures 2012. 2. Philpotts L, Raghu M, Durand M, et al.

Improving outcomes for women. i-medradiology.com.au Early Detection is the Key Doctors and scientists agree that early detection is the best defense against breast cancer. Successful treatment and survival rates for patients are dramatically improved by early detection. If lesions are found early, before spreading to lymph nodes, the five-year survival rate is almost 100 percent.1 thinking of the pages in a book. If you look down at the cover you cannot see all of the pages – but when you open it up, you can go through the entire book page-by-page to see everything between the covers. This is similar to how your images can now be viewed. Using 3D Tomosynthesis and 2D digital mammography together has been proven to significantly reduce “call-backs” by 20-40%.2, 3 In addition, 3D Tomosynthesis finds cancers earlier than 2D mammography alone, with a 27% increase in cancer detection and a 40% increase in invasive cancer detection.4 Until now, the best way to achieve this has been with mammography. Digital mammography provides a 2-dimensional picture of the breast and is the most advanced technologies available. However, the breast is a 3-dimensional object composed of different structures, such as blood vessels, milk ducts, fat, and ligaments. All of these structures, which are located at different depths within the breast, can overlap and maybe difficult to differentiate when viewed as a 2-dimensional, flat image. Overlapping tissue in some cases can be the reason for patients to be called back for further testing. Digital mammography has progressed to a new technology, 3D Tomosynthesis which has been shown to be superior to 2D digital mammography alone. What is 3D mammography? 3D mammography or 3D Breast Tomosynthesis is a new technology that allows our radiologists to examine your breast images/tissue one layer at a time. 3D Tomosynthesis uses high-powered computing to convert digital breast images into a stack of very thin layers or “slices” – building what is essentially a “3-dimensional mammogram”. A good analogy for 3D Tomosynthesis is like i-medradiology.com.au “When breast cancer is detected early, women have a much greater chance of being treated successfully.” Cancer Council Australia
