This project offers a comparison of 2D digital mammography (DM) and 3D digital breast tomosynthesis (DBT) to determine if one is more superior than the other in breast imaging. Types of mammography exams, different projections, breast cancer, equipment definitions, advantages, and disadvantages are also discussed. Breast cancer is one of the most common and most treatable types of cancer detected in women. Equipment is frequently evolving to better improve image quality and patient comfort. DM takes a stationary image of the compressed breast at one angle while DBT takes images in slices at multiple angles. This allows for better visualization of cancers from the surrounding breast tissue. This research indicates that 3D does have some advances compared to 2D imaging, but there is not a significant difference between their diagnostic capabilities. When DBT is used diagnostically, cancers are more visible, benign biopsies are reduced, less additional views are needed, and there is increased sensitivity and specificity. Since mammography equipment is always changing, further research may be necessary to compare 3D and 2D mammography in breast imaging.
