摘　　要：目的　探讨主动脉夹层磁共振成像技术及其临床应用。方法　 31例不同类型的主动脉夹层患者 ,在心电门控多层自旋回波序列下行横轴位、左前斜位、冠状位MRI扫描。结果　 31例均获得满意效果 ,其中Ⅰ型10例 ,Ⅱ型 3例 ,Ⅲ型 18例。在常规SE图像上可观察到破口位置、真假腔、内膜片及附壁血栓。结论　选择合适的扫描参数以及应用心电门控技术是确保获得高质量MRI影像的重要因素 ,作为一种无创性检查方法 。Objective To investigate MRI techniques and it's clinical application in aortic dissection.Methods 31 patients with different types of aortic dissection were examined by using ECG-gated spin echo sequence and gradient echo sequence to get axial or left anteri oroblique section and coronal section MR image.Results The reliable MRI image was obtained in all the 31 cases,including typeⅠ(10 cases),Ⅱ(3 cases),Ⅲ(18 cases).The entrance and exit sites,true and false channel,intimal flap and thrombos can be demonstrated on SE MR image.Conclusion As an invasive method,MRI have significant potential in the diagnosis and evaluation of patients with aortic dissection.The suitable scan paraments and successful ECG trigger is important factors for obtained high quality MR image.
