急性肺栓塞的影像检查技术应用进展

Advances in the application of imaging techniques for acute pulmonary embolism

急性肺栓塞(APE)是一类以骤然起病、进展迅速且死亡率高为特征的临床病理生理综合征。早期定性诊断和预后评估对于改善APE流行病学现状尤为重要。CT肺动脉血管成像、肺通气灌注显像、MR肺血管成像以及超声成像等影像检查方法在APE早期诊断、危险分层和预后评估中发挥着重要作用。就上述各种影像检查方法在APE定性检测及定量评估中的应用进展及限度进行综述。

Acute pulmonary embolism is a clinical pathophysiological syndrome with the characteristics of sudden onset,rapid progression,and high mortality.Early qualitative diagnosis and prognosis assessment are particularly important to improve the epidemiology of acute pulmonary embolism.Various medical imaging examinations,including computed tomography pulmonary angiography,ventilation/perfusion scintigraphy,MR pulmonary angiography,and ultrasonography play an important role in the early diagnosis,risk stratification,and prognosis assessment of acute pulmonary embolism.This aticle reviews the progress and limitations of the above-mentioned imaging techniques in the qualitative and quantitative assessment of acute pulmonary embolism.
