Despite the multiple advantages of digital imaging technology, the inherent disadvantages of mammography imaging have not disappeared. In mammography imaging, cancer is visualized as a white area within the background density of the breast. The sensitivity of the system will, therefore. depend on breast density, patient age, or patient hormone status. Mammography also tends to understate the multifocality of a lesion, and inadequate compression and poor positioning will affect interpretation. Therefore, 2-D imaging is not 100% effective as an imaging tool; it is limited by tissue superimposition. These overlapping tissues can mask or mimic tumors, leading to false-negative or false-positive reports. To minimize the disadvantages of 2-D imaging, the concept of 3-D imaging, or digital breast tomosynthesis, was incorporated in breast screening and diagnostic workups.


3-D mammography is fast becoming the modality of choice when imaging the breast. The technology is easy to use with a minimum learning curve for technologists already familiar with 2-D digital mammography imaging. This course will compare the various 3-D options available and describe the advantages and disadvantages of this new technology. After studying the information presented here, you will be able to:
  • Explain the advantages and disadvantages of 2-D and 3-D breast-cancer screening.
  • Discuss breast cancer screening using tomosynthesis techniques.
  • Identify differences between tomosynthesis techniques.
