Abstract

Dual-energy computed tomography (DECT) has become increasingly available and can be readily incorporated into clinical practice. Although DECT can provide a wide variety of spectral imaging reconstructions, most clinically valuable information is available from a limited number of standard image reconstructions including virtual non-contrast and iodine overlay. The combination of these standard reconstructions can be used for specific diagnostic tasks that provide added value over traditional CT protocols. In this pictorial essay, the added value of these standard reconstructed images will be demonstrated by case examples for diseases specifically related to the gastrointestinal system.

摘要

双能计算机断层扫描（DECT）已越来越普及，并且可以很容易地应用于临床实践。尽管DECT可以提供各种各样的光谱成像重建，但大多数具有临床价值的信息可从有限数量的标准图像重建中获得，包括虚拟平扫和碘叠加。这些标准重建的组合可用于特定的诊断任务，与传统CT方案相比能提供更多价值。在这篇图文并茂的文章中，将通过与胃肠系统具体相关疾病的病例实例来展示这些标准重建图像的附加价值。
