肺动脉栓塞诊断的现代策略

The Current Diagnostic Strategy of Pulmonary Embolism

肺动脉栓塞是一种致 死率很高的疾病,已引起国内外医学界的重视。确立一个准确、无创、简单易行、高效价比和能广泛应用的诊断方法是至关重要的。核素肺通气/灌注扫描(V/O)诊断的不足,肺动脉造影检查的有创性,被近年发展起来的CT和MRI技术所补偿逐步形成了肺动脉栓塞现代诊断策略。电子束CT或螺旋CT被成功作为一线的筛选工具,确诊肺动脉栓塞准确性达90％-100％。

Acute pulmonary embolism is a frequent disease with high mortality. A definitive diagnosis must be established by accurate, non-invasive, easily performed, cost-effective, and widely available imaging modahties. In this article, variant medical images were evaluated. Recently, marked improvements in CT and MRI and shortcomings of scintigraphy led to an update of the current diagnostic strategy. Electron beam CT(EBCT) and spirai CT are successfully employed as the first-line screening tools. The accurate diagnostic rate of pulmonary embolism is 90%-100%.
