Lesion Localization Using Digital Breast Tomosynthesis: Where Did I Go Wrong?

The scroll bar on digital breast tomosynthesis has become an imperative tool that breast imaging radiologists rely on for help in identify lesions on the orthogonal view, targeting breast ultrasound, and performing challenging biopsies for one-view findings. The ability to predict the lesion location using the scroll bar not only saves time in the diagnostic setting but also reduces screening recalls when a finding can be confirmed as dermal. It is important, however, to recognize settings in which the location prediction can be misleading, such as for lesions in thin breast tissue or the anterior portion of the breast or if the breast is not appropriately positioned. In these situations, radiologists can use other diagnostic tools for problem solving.
