TRIANGULATION IN BREAST IMAGING The challenge of locating lesions in their appropriate three-dimensional relationship to the breast is one of the more difficult responsibilities of the breast-imaging radiologist. Dr. Eklund’s highly regarded lectures on the subject of Triangulation form the basis of this publication. This topic is presented in a clear and well-illustrated manner that will give the reader a new perspective and expertise on locating lesions that are seen on one view only. The importance of using triangulation in establishing concordance of lesions seen in two or more images, or between sonographically apparent lesions and mammographic findings, is stressed. This iBook is written for those who practice, those who prepare new colleagues to practice and those who aspire to practice breast-imaging radiology.
