ABSTRACT

Even well into the 21st century, breast cancer still claims thousands of lives every year in the United States (US). Some patient populations are more susceptible to missed diagnoses, particularly those with dense breasts. However, digital breast tomosynthesis (DBT) has proven to be a helpful radiologic tool to assist with catching breast cancer early during breast screenings. Combined with other modalities, DBT provides views and angles that may not be able to be achieved using digital mammography alone. To that end, it is crucial that breast imaging radiologic technologists and mammographers working with DBT are kept up-to-date about the latest data and information in order to effectively perform this imaging study and provide the best possible patient care. This course will review the impact that breast cancer has had in the US and how a patient's age, medical and family history, and breast density impact their risk of being diagnosed with breast cancer. A review of breast anatomy will be detailed as will a description of the most commonly diagnosed types of breast cancer and various treatment options. An overview of breast cancer tumor staging, breast density descriptors and reporting procedures, and national and local legislation requiring patient notification regarding their breast density will also be given. The role of DBT in screening patients for breast cancer and how best to utilize it along with other forms of mammography will be discussed. Finally, DBT functionality, equipment, processes, image acquisition, quality control, and radiation safety considerations will all be highlighted.
