Elastography is a newly emerging study of interest that can be especially helpful when used as an adjunct to conventional B-mode ultrasound in evaluating breast lesions. It is estimated that 80% of breast lesions currently biopsied prove to be benign. Reducing that percentage is advantageous to both patients and the imaging community. The specificity of conventional ultrasound when added to a mammography work-up needs improvement. Adding elastography may improve specificity. This Directed Reading describes different acoustic techniques used to obtain an elastogram and evaluation of scoring procedures. Major technique differences exist in imaging the elastic properties of tissue. This article is a Directed Reading.

弹性成像技术是一项新兴的研究领域，在辅助传统B超评估乳腺病变时特别有用。据估计，目前活检的乳腺病变中有80%被证明是良性的。降低这一比例对患者和影像学领域都有益。传统超声在乳腺钼靶检查流程中的特异性有待提高。增加弹性成像技术可能会提高特异性。这篇定向阅读文章描述了用于获取弹性图的不同声学技术以及评分程序的评估。在对组织弹性特性成像方面存在主要技术差异。本文是一篇定向阅读文章。你能否通过定向阅读测验获得继续教育学分取决于你的继续教育偏好。如需访问其他测验，请访问www.asrt.org/store。
