In mammography, which technique is primarily utilized to confirm abnormalities?

The triangulation technique is primarily utilized to confirm abnormalities in mammography because it allows for accurate localization of lesions. This method involves taking images from different angles, which helps radiologists pinpoint the position of an abnormality relative to surrounding anatomy. By correlating the findings from various views, it enhances the detection of small or subtle lesions that may not be as apparent on a single view or standard imaging technique.

Triangulation aids in distinguishing between true abnormalities and normal breast tissue variations by providing a clearer understanding of the spatial relationships within the breast. This improves the accuracy of further diagnostic procedures, such as biopsies or additional imaging, as it allows for a more focused approach to areas of concern.

The other techniques play essential roles in mammography but serve different purposes. Digital compression, for instance, enhances image quality and reduces the thickness of breast tissue during imaging, aiding in better visualization rather than confirming abnormalities. Similarly, 3D mammography, while effective in providing a clearer picture of breast structures, is primarily utilized for improved detection rather than direct confirmation of abnormalities. Contrast-enhanced mammography offers additional detail for specific cases but is used selectively and is not the primary method for confirming abnormalities.
