Over the past 10 years, spiral CT angiography of the pulmonary arteries has reached a high accuracy in the evaluation of pulmonary embolism. Major advantages of CT compared with ventilation/perfusion lung scintigraphy and pulmonary angiography is direct visualization of clots in the pulmonary arteries, and to provide alternative findings or diagnosis. The recent introduction of multislice CT has improved the evaluation of peripheral pulmonary arteries, enabling high-resolution CT examinations over the entire thorax in a short breathhold. The examination techniques, imaging findings, pitfalls, and results of CT in the diagnosis of pulmonary embolism are reviewed in comparison with other diagnostic tests.
在过去10年中，肺动脉螺旋CT血管造影在评估肺栓塞方面已达到很高的准确性。与通气/灌注肺闪烁显像和肺动脉造影相比，CT的主要优势在于能直接观察到肺动脉内的血栓，并提供其他的发现或诊断。多层螺旋CT的近期应用改善了对周边肺动脉的评估，能够在一次短暂屏气期间对整个胸部进行高分辨率CT检查。本文将CT在肺栓塞诊断中的检查技术、影像表现、陷阱及结果与其他诊断检查进行比较后予以综述。
