The increasing availability of dual-energy CT (DECT) has set the stage for an exciting era in CT technology. This technique is extensively used throughout the world with numerous centres working on the applications of DECT in various radiology subspeciality areas. DECT provides many advantages over the conventional single-energy scan. Instead of a single set of images, radiologists have access to multiple sets of images from a single acquisition. The DECT workstation enables the reader to generate images, according to the clinical setting, in order to answer a specific clinical question. Radiologists should be aware of the basic concepts of DECT and the usefulness of each image data set. This article aimed to describe the basic principles, techniques and applications of DECT in the imaging of salivary gland lesions. The specific roles of each image data set, in the context of salivary gland lesions, are also discussed.
双能CT（DECT）可用性的不断提高为CT技术开启了一个令人兴奋的时代。这项技术在全球范围内被广泛应用，众多中心都在致力于DECT在各个放射学亚专业领域的应用。与传统单能扫描相比，DECT具有许多优势。放射科医生不再是获得一组单一的图像，而是可以从一次采集获取多组图像。DECT工作站使阅片者能够根据临床情况生成图像，以回答特定的临床问题。放射科医生应该了解DECT的基本概念以及每个图像数据集的用途。本文旨在描述DECT在唾液腺病变成像中的基本原理、技术和应用。还讨论了每个图像数据集在唾液腺病变背景下的具体作用。
