急性肺栓塞CT肺动脉成像的研究进展

Progresses of CT pulmonary angiography in acute pulmonary embolism

目前,CT肺动脉成像(CTPA)被认为是临床诊断急性肺栓塞(PE)的"金标准"。CTPA为诊断急性外周性PE提供了多方面的依据。但CTPA诊断急性外周性PE仍存在较大困难。目前CT辐射剂量及对比剂负荷为研究热点。本文对急性PE的CTPA诊断(尤其是外周性PE)、预后评估、CTPA技术进展等进行综述。

CT pulmonary angiography （CTPA） has become the clinical ＂gold standard＂ for diagnosis of acute pulmonaryembolism （PE）. CTPA provides many reliable basis in diagnosis of PE. But diagnosis of acute peripheral PE with CTPAremains difficult. CT radiation dose and contrast load have become hot research topics. The current progresses of acute PEin diagnostic methods of CTPA, prognostic assessment and technological improvement were reviewed in this article.
