现代双能 CT (DECT) 扫描仪的引入使得能够在成像时区分造影剂，而无需单独的非增强扫描。使用 DECT 获得的肺实质对比增强图像可改善缺陷的检测，增强我们检测肺栓塞的能力；然而，这些进步也带来了新的陷阱。在这篇图片综述中，我们介绍了双能量肺实质增强缺陷治疗肺栓塞的技术、临床应用以及错误结果的原因和补救措施。
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.
