磁共振三维增强肺动脉造影诊断肺动脉血栓栓塞及临床应用的初步研究

Diagnosis and Clinical Application of Three-Dimensional Contrast Enhanced MR Pulmonary Angiography

目的 研究屏气三维增强磁共振肺动脉造影的方法和临床应用。方法 3 5例病人经过屏气三维增强磁共振肺动脉造影检查 ,19例曾做过核素扫描 ,3例做过CT肺动脉增强扫描 ,3例做过肺动脉DSA。结果 本文分析了肺栓塞的三维增强磁共振肺动脉造影的图像特征表现 ,3 5例中 2 9例发现肺栓塞 ,主要征象包括腔内充盈和管腔闭塞。结论 屏气三维增强磁共振肺动脉造影是确诊肺栓塞的一种无创、有效的检查手段 。

Purpose To investigate the methods,and clinical value of breath hold three dimensional contrast enhancement magnetic resonance angiography. Methods A total of 35 consecutive patients with suspected pulmonary embolism underwent breath hold 3D CE MRPA.Nineteen patients were examined by SPECT,3 patients by selective pulmonary DSA. Results Pulmonary embolism was detected by 3D CE MRPA in 29 of the 35 patients. Primary features included embolus and obstruction in pulmonary artery. Conclusion Breath hold 3D MRPA has proved to be a non invasive and useful tool in detection of pulmonary embolism. It has good prospect of clinical application.
