CE—MRA与DSA下颈内动脉狭窄率的比较研究

To study the difference in the stenosis rate of the internal carotid artery under the CE- MRA and DSA

目的比较增强颈部血管核磁成像术（CE—MRA）与血管造影技术（DSA）下颈内动脉狭窄率有无显著性的差异。方法收集133例CE—MRA与DSA均提示右侧颈内动脉C1段狭窄的影像学的资料，采用NASCET（北美颈内动脉内膜切除术）法测量其狭窄率。结果两组检查方法无统计学的差异（P〉0．05）。结论CE—MRA检测颈内动脉c1段的狭窄率是真实可信的。

Objective To compare if there is a significant difference in the stenosis rate ofthe internal carotid artery under the CE- MRA and DSA. Methods 133 cases of CE-MRA and DSA were prompted C1 segment stenosis of the right internal carotid artery ofimage data,were measured the stenosis rate using NASCET （North American carotidendarterectomy） method. Results Both groups had no statistical difference in inspectionmethods （P〉 0.05）. Conclusion CE-MRA test stenosis rate in the C1 segment of theinternal carotid artery is authentic.
