摘要

目的探讨增强磁共振血管成像（CE-MRA）技术在颈部动脉疾病诊断中的应用价值。方法选择2013年1月~2014年6月我院收治的106例颈部动脉血管病变患者，所有患者均进行CE-MRA检查，并与数字减影血管造影（DSA）结果进行对比，比较两种检查方法的检出率。结果 DSA检出106例动脉狭窄，118处狭窄段；CE-MRA检出101例动脉狭窄，112处狭窄段，两者相比无统计学差异（P>0.05）。DSA检出轻度狭窄（＜50%）46处，中、重度狭窄（50%～95%）52处，完全闭塞（≥95%）20处；CE-MRA检出轻度狭窄44处，中、重度狭窄49处，完全闭塞19处，两者相比无统计学差异（P>0.05）。结论 CE-MRA检查对颈部动脉疾病具有较高的检出率，且医源性创伤较低，可作为颈部动脉疾病诊断的首选检查方案。

Abstract

Objective To discuss the effectiveness of application of contrast enhanced magnetic resonance angiography (CE-MRA) in diagnosis of carotid artery diseases (CAD). Methods Altogether 106 CAD patients who had been treated in the hospital from January 2013 to June 2014 were selected as the research object. All the patients had been scanned by both CE-MRA and DSA so as to compare the detection rate between two methods. Results Altogether 118 stenosis segments were revealed by DSA in 106 patients with artery stenosis. While, CE-MRA detected 101 cases of arterial stenosis with 112 stenosis segments. No statistically significant differences existed between two diagnostic results (P>0.05). DSA displayed 46 slight stenosis segments (<50%), 52 moderate and severe stenosis segments (50%~95%), and 20 complete occlusion segments (≥95%) in comparison with 44 slight stenosis segments, 49 moderate and severe stenosis segments, and 19 complete occlusion segments detected by CE-MRA. No statistically significant differences were seen between two diagnostic results (P>0.05). Conclusion CE-MRA had proven its effectiveness in high detection rate in diagnosis of CAD and low iatrogenic traumas, which could be taken as the first choice for diagnosis of CAD.
