目得：为探讨磁共振（MR）肺动脉造影在20例临床怀疑肺栓塞（PE）患者中的准确性，材料与方法：14例患者（第1组）在根据临床表现进行常规肺动脉造影（CPA）之前进行MR肺动脉造影研究。6例患者（第2组）未接受CPA，但根据其他研究的结果被认为患有PE。结果：MR肺动脉造影诊断PE的敏感性为92%~ 100%，特异性为62%。MR肺动脉造影和MR静脉造影在一个单一的检查，以证明血栓在动脉和深静脉system.CONCLUSION：本报告描述了一个新的MR肺血管造影技术的早期临床实施的性能是可行的。在常规临床使用MR肺血管造影证明合理之前，通过增强对慢血流的敏感性和提高空间分辨率来提高特异性的进一步进展是必要的。
PURPOSE: To study the accuracy of magnetic resonance (MR) pulmonary angiography in 20 patients in whom pulmonary embolism (PE) was clinically suspected.MATERIALS AND METHODS: Fourteen patients (group 1) were recruited for the MR pulmonary angiography study before they underwent conventional pulmonary angiography (CPA) based on clinical findings. Six patients (group 2) did not undergo CPA but were considered to have PE on the basis of findings in other studies. MR venography was performed at the time of MR pulmonary angiography in 13 patients.RESULTS: MR pulmonary angiography had a sensitivity of 92%-100% and specificity of 62% for detection of PE. Performance of MR pulmonary arteriography and MR venography in a single examination to demonstrate thrombus in both the arterial and deep venous systems was proved feasible.CONCLUSION: This report describes an early clinical implementation of new MR pulmonary angiographic techniques. Further advances to improve specificity by enhancing sensitivity to slow flow and increasing spatial resolution are necessary before routine clinical use of MR pulmonary angiography is justified.
