【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. 【总页数】4页(1006-1008,1027)
