64排螺旋CT肺血管成像在肺动脉栓塞诊断中的临床应用

目的讨论64排螺旋CT肺血管成像结合多种图像后处理方式在肺动脉栓塞诊断中的临床应用。方法选取2009年1月至今疑似肺动脉栓塞患者的临床资料64例,选用不同的图像后处理方式,进行回顾性诊断分析。结果 64例患者的检出情况,在1级动脉MPR、MIP、VR三种处理方式无任何差别;在2-3级动脉血管MPR检出率较高,与MIP和VR差异显著,具有统计学意义(P<0.05);在4-5级动脉血管MPR也高于MIP和VR,但是结果不具有统计学意义(P>0.05)。结论 CTPA诊断在诊断肺栓塞方面,结合多种图像后处理方式能增大疾病的检出率,有助于PE确切的疗效评价,做到疾病的早期诊断,可以显著地降低病死率,为外科手术治疗提供参考依据。

64-slice Spiral CT Pulmonary Angiography in the Diagnosis of Pulmonary Embolism

Objective To discuss 64-slice spiral CT pulmonary angiography(CTPA) with a variety of image processing methods in the diagnosis of pulmonary embolism(PE).Methods The clinical data of 64 cases with suspected PE were selected since January 2009,from which a retrospective diagnosis was made with different image processing methods.Results When examining arteries in 1 level,there was no significant difference between MPR,MIP and VR in detection rate.For arteries in 2-3 level,MPR had a higher detection rate,which was significantly different from MIP and VR(P <0.05).For arteries in 4-5 level,MPR also had a higher detection rate than MIP and VR,but the results showed no statistical significance(P> 0.05).Conclusions Combined with a variety of image processing methods,CTPA can increase the detection rate of PE,which is conducive to the early diagnosis,clinical evaluation and reduction of mortality,providing a basis for surgical treatment.
