MRI Evaluation of Aortic Aneurysms

分析了21例23个主动脉瘤MRI表现,并讨论了MRI的诊断特点。MRI能正确显示主动脉瘤的部位、形态、范围和大小,并能显示瘤壁、附壁血栓、主动脉分支及周围结构的受累情况,故MRI能较全面地反映主动脉瘤的全貌。MRI虽不能取代超声心动图的首选检查地位。但可对此作重要补充,两者结合在多数病例中可免去创伤性的主动脉造影。

We analysed MRI findings of 23 aortic aneurysms in 21 cases and disscused the MRI features in examining aortic aneurysms. MRI could adequately defined the location, morphology, size and extent of the aneurysms, and also well showed the wall, intraluminal thrombus and involvement of major aortic branches and perivascular structures, So MRI could more completely evaluated the aortic aneurysms. UCG still remains as an initial method in suspected aortic aneurysms, MRI should be reserved for further evaluation. MRI combining UCG can likely avoid invasive aortography in most cases.
