中文摘要：双能量CT(DECT)应用两种能量、两套探测器，根据不同能量下物质衰减特性的差异进行定性及定量的数据采集。DECT具有高分辨率、易获得等优势，通过后处理技术，从形态学、功能学两方面获取疾病信息。近年来，DECT在肺血管疾病如肺栓塞、慢性血栓栓塞性肺动脉高压、动脉型肺动脉高压、肺静脉闭塞性疾病/肺毛细血管瘤等诊治中展现出优越的作用。现从DECT的技术原理及其在肺血管疾病中的应用进展做一综述。

外文标题：Dual-Energy CT Imaging in Pulmonary Vascular Diseases

外文摘要：Dual-energy CT(DECT)collects qualitative and quantitative data based on the difference in material attenuation characteristics under different energies using two types of energy and two sets of detectors.DECT provides the benefits of easy access and high resolution.Disease information can be obtained from morphology and function using post-processing techniques.DECT has shown superiority in the diagnosis and treatment of pulmonary vascular diseases such as pulmonary embolism,chronic thromboembolic pulmonary hypertension,pulmonary arterial hypertension,and pulmonary venous occlusive disease/pulmonary capillary hemangiomatosis.This article reviews the technical principles of DECT and its application progress in pulmonary vascular diseases.
