螺旋CTPA与MRPA诊断肺动脉栓塞的对比分析

A Contrastive Analysis of Spiral CTPA and MRPA in the Diagnosis of Pulmonary Embolism

目的 :通过对肺动脉栓塞的CT与MRI征象的分析和比较 ,探讨肺动脉栓塞的CTPA与MRPA的特征性表现 ,提高肺栓塞的CTPA与MRPA诊断应用价值。方法 :对 2 4例临床和DSA证实为肺动脉栓塞的患者 ,行螺旋CT肺动脉造影 (CTPA)和MR肺动脉造影 (MRPA) ,请两位以上的有经验的医生 ,将CTPA及MRPA的征象进行归类、统计学分析。结果 :2 4例患者CTPA检出病变 (血栓 ) 2 3例占 95 83% ,累及肺动脉主干或其分支有 4 6处。MRPA检出病变 2 1例占 87 5 % ,累及肺动脉及其分支 37处。结论 :在肺动脉栓塞的诊断中 ,CTPA较MRPA敏感 ,可作为肺动脉栓塞的无创伤性影像学检查的首选。

Objective:To investigate CT and MRI features of pulmonary embolism and improve diagnosing value of CTPA and MRPA through analysis and comparison the CTPA and MRPA signs. Methods:The imaging features of 24 cases which confirmed by clinic and DSA were analyzed by two salty doctors.The signs of CTPA and MRPA performed spiral CTPA and MRPA were grouped and statistics analyzed.Resluts:Resluts Of all the 24 cases,23cases (95.83%) were detected on CTPA and 46 main pulmonary arteries or branches were involved; Whereas on MRPA,21cases (87.5%) were detected and 37 main pulmonary arteries or branches were involved.Conclusion:CTPA is sensitiver than MRPA and as an invasive method can be first choice on diagnosing pulmonary embolism.
