OBJECTIVE
The purpose of this article is to discuss the diagnostic role of pulmonary CT angiography (CTA) in the workup of pulmonary embolism (PE), including specific populations, and issues such as pulmonary CTA combined with indirect CT venography; radiation dose considerations; the management of isolated subsegmental PE; and new technologic developments, such as dual-source/dual-energy pulmonary CTA.
CONCLUSION
The role of pulmonary CTA will continue to grow with the emergence of MDCT and dual-energy CT and their improved capabilities. However, the need for any given CT examination should always be justified on the basis of the individual patient's benefits and risks.
目的
本文旨在讨论肺部 CT 血管造影（CTA）在肺栓塞（PE）检查中的诊断作用，包括特定人群，以及肺部 CTA 与间接 CT 静脉造影相结合的问题；辐射剂量问题；孤立性亚段肺栓塞的处理；以及新技术的发展，如双源/双能肺部 CTA。
结论
随着多层 CT 和双能 CT 及其功能的改进，肺部 CTA 的作用将不断扩大。然而，任何特定 CT 检查的必要性都应始终根据患者的个体获益和风险来确定。
