Abstract

Dual-energy computed tomography (CT) is a promising tool, providing both anatomical information and material properties. Using spectral information such as iodine mapping and virtual monoenergetic reconstruction, dual-energy CT showed added value over pulmonary CT angiography in the diagnosis of pulmonary embolism. However, the role of non-contrast-enhanced dual energy CT in pulmonary embolism has never been reported. Here, we report a case of acute pulmonary embolism detected on an electron density image from an unenhanced dual-energy CT using a dual-layer detector system.

摘要

双能计算机断层扫描(CT)是一种很有前景的工具,可提供解剖学信息和物质特性。利用碘成像和虚拟单能量重建等光谱信息,双能CT在肺栓塞诊断中显示出优于肺CT血管造影的附加价值。然而,非增强双能CT在肺栓塞中的作用尚未见报道。在此,我们报告一例使用双层探测器系统的非增强双能CT电子密度图像上检测到的急性肺栓塞病例。
