摘要
目的 探讨主动脉夹层的影像学诊断方法 .评价CT及MRI检查诊断主动脉夹层的优势.方法 收集并回顾性分析笔者所在医院30例主动脉夹层患者的X线平片,CT、MRI检查及临床资料.对检查结果 进行汇总分析.结果 X线平片提示阳性率63.3%（19/30）;CT阳性率93.3%（28/30）,检测出破裂口9例,检出率30.0%;MRI检查阳性率100.0%（30/30）,均清晰显示出真假两腔和内膜片,20例检出破口,检出率66.7%,1例有附壁血栓.结论 MRI检查主动脉夹层具有特征性影像表现.CT、MRI检查是诊断主动脉夹层快捷实用、准确性高、无创性的影像学检查方法 .
Objective To explore the imaging diagnosis of aortic dissection method. Evaluation of CT and MRI the diagnosis of arterial dissection advantage. Methods Collected and analyzed retrospectively 30 cases of aortic dissection in our hospital cases of X - ray, CT, MRI and clinical data. Check the results of the meta- analysis. Results The results of X - ray film suggestive positive rate of 63.3% （19/30） ; CT posi- tive rate of 93.3% （28/30）detected nine cases of rupture of mouth, and the detection rate of 30. 0% ; MRI- positive rate was 100. 0% （30/30 ）, are clear and show true and false two chambers and intimal flap ,20 cases detected crevasse, and the detection rate of 66.7%. 1 case had mural thrombus. Conclusion MRI examination of aortic dissection has a relatively characteristic imaging findings. CT, MRI examination is quick diag- nosis of aortic dissection and practical, high accuracy, non - invasive imaging examination methods.
