Abstract
The introduction of modern dual-energy CT (DECT) scanners has enabled contrast material to be distinguished at imaging without the need for a separate unenhanced scan. Images of pulmonary parenchymal contrast enhancement obtained using DECT improve the detection of defects, augmenting our ability to detect pulmonary emboli; however, with these advances new pitfalls are also introduced. In this pictorial review, we present the technique, clinical applications and causes and remedies of false results of dual-energy pulmonary parenchymal enhancement defects in pulmonary embolism.
摘要
现代双能 CT（DECT）扫描仪的引入使得在成像时无需进行单独的未增强扫描即可区分造影剂。使用 DECT 获得的肺实质对比增强图像可提高对缺陷的检测能力，增强我们检测肺栓塞的能力；然而，随着这些进展，新的陷阱也随之而来。在本图片综述中，我们介绍了双能肺实质增强缺陷在肺栓塞中的技术、临床应用以及导致假阳性和假阴性的原因和补救措施。
