摘要
肺栓塞是常见的心胸部血管急症之一,其主要致死并发症为其导致的右心功能不全。CT肺动脉成像为临床诊断肺栓塞首选的影像检查方法。本文对肺栓塞及右心功能不全在CT肺动脉成像中的影像特征及机制、目前CT肺动脉成像临床应用现状及局限性、CT肺动脉成像技术进展等进行综述。
Pulmonary embolism is one of the common cardiothoracic vascular emergencies,and its main fatal complication is right ventricular dysfunction.CT pulmonary angiography is the preferred imaging method for clinical diagnosis of pulmonary embolism.This article reviews the imaging characteristics and mechanism of pulmonary embolism and right heart dysfunction in CT pulmonary angiography,the current clinical application status and limitations of CT pulmonary angiography,and the progress of CT pulmonary angiography technology.
