Breast Tomosynthesis offers an additional screening tool in the fight against breast cancer. Breast Tomosynthesis is the most up-to-date method of breast cancer screening and diagnosis.
With an approximate 10% increase in sensitivity, breast tomosynthesis provides physicians with images that have even greater detail and clarity. The clear pictures provided by 3D Mammography improves the detection of cancer and lesion visibility and can decrease recall rates by 20-40%.
For the patient,there is no change in how the images are obtained. Just as in a routine mammogram, Breast Tomosynthesis images are obtained with the breast held briefly in compression. While digital mammography remains one of the most advanced technologies,the difference is that traditional mammograms only take one picture across the entire breast, from top to bottom and side to side. The rotating exposure of Breast Tomosynthesis lasts for approximately 10 seconds longer, but the result is a stack of image slices, similar to a CT scan,that provides clear breast detail. This can eliminate “false positive”readings caused by overlapping tissue or dense breasts, and better detect very small cancers.
