主动脉夹层动脉瘤不同放射影像学对比分析

Comparative analysis of different radiographic imaging of aortic dissecting aneurysm

目的:对比CT与MRI诊断主动脉夹层动脉瘤(ADA)的临床价值。方法:选取2019年5月—2021年2月我院58例ADA患者作为研究对象,所有患者分别行CT诊断与MRI诊断,采用平扫与增强扫描相结合的方式,对比两种诊断方式对ADA的检出率及分型情况,总结影像学特点。结果:MRI及CT对ADA均具有较高的检出率,能够准确对ADA进行分型,清晰显示出ADA真假腔、内膜片及内膜破口情况等,帮助了解主动脉扩张、狭窄及分支血管受累情况。结论:CT、MRI诊断ADA灵敏度、特异度高,有利于实现对ADA的分型,两者优势互补,可结合患者实际情况选择合适诊断方式。

Objective To compare the clinical value of CT and MRI in the diagnosis of aortic dissecting aneurysm(ADA).Methods From May 2019 to February 2021,58 ADA patients in our hospital were selected as the research objects.All patients were diagnosed by CT and MRI respectively.The combination of plain scan and enhanced scan was used to compare the two diagnostic methods for ADA.The detection rate and classification status of the patients,and the imaging characteristics are summarized.Results Both MRI and CT have a high detection rate for ADA,which can accurately classify ADA,clearly show the true and false cavities,endometrial slices,and endometrial ruptures of ADA,and help understand the dilation,stenosis,and rupture of the aorta.Involvement of branch vessels.Conclusion CT and MRI have high sensitivity and specificity in diagnosing ADA,which is beneficial to the classification of ADA.The advantages of the two complement each other,and the appropriate diagnosis method can be selected according to the actual situation of the patient.
