多层螺旋CT血管造影对肺动脉栓塞的诊断

Diagnosis value of multi-slice spiral CT angiography to pulmonary embolism

目的:评价多层螺旋CT肺动脉血管造影(CT pulmonary angiography,CTPA)对肺动脉栓塞(pulmonary embolism,PE)的诊断价值。方法:回顾分析临床确诊为肺动脉栓塞的10例患者的CTPA图像的表现。结果:10例PE共累及58处肺动脉及分支,其中左肺动脉主干7处,右肺动脉主干8处,肺叶动脉15处,肺段动脉28处。结论:多层螺旋CTPA具有准确、快速、无创伤等优点,可立体、直观地观察到血栓的大小、分布及范围,并可观察肺内间接改变,是PE的临床诊断及观察疗效的首选方法。

Objective： To evaluate the value of multi-slice spiral CT angiography（CTPA）in the diagnosis of pulmonary embolism（PE）.Methods： The CTPA images of ten patients clinically diagnosed with PE were retrospectively analyzed.Results： It was discovered that the embolisms involved 58 main and branches of the pulmonary arteries in all 10 cases with PE,including 8 right main pulmonary arteries,7 left main pulmonary arteries,15 lobular pulmonary arteries and 28 segmental pulmonary arteries.Conclusion： multi-slice spiral CT angiography is an accurate,quick and noninvasive method in the diagnosis of PE,which can help us to observe the size,distribution and area of the embolism three-dimensionally and intuitively,and to observe the indirect changes in lungs.It is an optimal method for the clinical diagnosis of PE and has therapeutic evaluation.
