Abstract

Dual energy computed tomography is becoming increasingly widespread in clinical practice. It can expand on the traditional density-based data achievable with single energy computed tomography by adding novel applications to help reach a more accurate diagnosis. The implementation of this technology in cardiothoracic vascular imaging allows for improved image contrast, metal artifact reduction, generation of virtual unenhanced images, virtual calcium subtraction techniques, cardiac and pulmonary perfusion evaluation, and plaque characterization. The improved diagnostic performance afforded by dual energy computed tomography is not associated with an increased radiation dose. This review provides an overview of dual energy computed tomography cardiothoracic vascular applications.

摘要

双能计算机断层扫描在临床实践中越来越普遍。通过添加新的应用以帮助实现更准确的诊断，它可以扩展单能计算机断层扫描所能获得的基于传统密度的数据。该技术在心胸血管成像中的应用可提高图像对比度、减少金属伪影、生成虚拟平扫图像、虚拟钙减影技术、心脏和肺部灌注评估以及斑块特征分析。双能计算机断层扫描所提供的更高的诊断性能与辐射剂量增加无关。本文综述了双能计算机断层扫描在心胸血管方面的应用。
