三维增强磁共振血管成像和数字减影血管造影在颈部动脉狭窄闭塞性病变中的对比分析

摘要

目的 评价三维增强磁共振血管成像(3D-CE-MRA)诊断颈部动脉狭窄闭塞性病变的准确性及应用价值.方法 对43例可疑颈部动脉狭窄或闭塞的患者分别先后进行3D-CE-MRA和数字减影血管造影(DSA)检查,对成像结果进行对比研究.结果 与DSA相比,3D-CE-MRA 对颈部动脉狭窄闭塞性病变诊断的敏感度为83.0%,特异度为94.1%.结论 3D-CE-MRA对颈部动脉狭窄闭塞性病变的显示具有独特的优势,是一种无创、安全、快速、准确性高的检查方法,可以作为首选的检查方法.%Objective To evaluate the accuracy and application of 3D contrast-enhanced MR angiography(CE-MRA) in diagnosis of carotid artery stenosis. Methods 3D-CE-MRA and digital subtraction angiography (DSA) were performed in 43 cases suspected with carotid arterial stenosis. The results in showing carotid arterial stenosis by 3D-CE-MRA and DSA were evaluated comparatively. Results Compared with DSA,the sensitivity and specificity of 3D-CE-MRA in diagnosis of carotid artery stenosis were 83. 0% and 94. 1% ,respectively. Conclusion As one of the invasive method,3D-CE-MRA has special advantage and will be the primary examination in diagnosis of carotid artery stenosis.
