摘　　要：目的 探讨三维动态增强磁共振血管壁成像(3D CE-MRA)对颈动脉蹼的诊断价值,为颈动脉蹼的诊断提供参考依据。方法 选择2020年2月-2022年8月邢台市第三医院收治的110例疑似颈动脉蹼患者作为研究对象,所有患者均于入院后行计算机断层扫描血管造影术CTA)、3D CE-MRA和颈动脉超声检查,以CTA检查结果为“金标准”,分析3D CEMRA与颈动脉超声诊断颈动脉蹼的准确性,并比较3D CE-MRA诊断颈动脉蹼患者血管狭窄程度与CTA检查结果的一致性。结果 根据CTA检查结果显示,110例疑似颈动脉蹼患者中,确诊颈动脉蹼94例,其中管腔轻度狭窄46例,中度狭窄28例,重度狭窄20例。3D CE-MRA诊断颈动脉蹼的敏感度和准确度高于颈动脉超声,差异有统计学意义(P<0.05);3D CE-MRA与颈动脉超声诊断颈动脉蹼的特异度比较,差异无统计学意义(P>0.05)。经Kppa一致性检验,3D CE-MRA诊断颈动脉蹼患者血管狭窄程度与CTA检查结果的一致性高(Kappa=0.782,P<0.001)。结论 3D CE-MRA在颈动脉蹼的诊断中具有较高的应用价值,且其诊断颈动脉蹼患者血管狭窄程度与CTA检查结果的一致性高。Objective To explore the diagnostic value of three-dimensional contrast-enhanced mag-netic resonance angiography(3D CE-MRA)for carotid web,and to provide reference for the diagnosis of carotid web.Methods A total of 110 suspected carotid web patients admitted to Xingtai Third Hospital from February 2020 to August 2022 were selected as the study subjects.All patients underwent computed tomography angiography(CTA)and 3D CE-MRA examination and carotid ultrasound after admission.With the CTA results as the gold standard,the accuracy of 3D CE-MRA and carotid ultrasound in the diagnosis of carotid artery web was analyzed,and the consistency of 3D CE-MRA and carotid ultrasound in the diagnosis of carotid artery web patients with stenosis was compared with the CTA results.Results According to the CTA examination results,out of 110 suspected patients with carotid web,94 were diagnosed with carotid web,including 46 cases of mild stenosis,28 cases of moderate stenosis,and 20 cases of severe stenosis.The sensitivity and accuracy of 3D CE-MRA in the diagnosis of carotid web were higher than those of carotid ultrasound,and the difference was statistically significant(P<0.05).There was no statistical significant difference in the specificity of 3D CE-MRA and carotid ultrasound in the diagnosis of carotid web(P>0.05).According to the Kappa consistency test,the degree of vascular stenosis diagnosed by 3D CE-MRA in patients with carotid web was highly consistent with the results of CTA examination(Kappa=0.782,P<0.001).Conclusion 3D CE-MRA has high application value in the diagnosis of carotid web,and its diagnosis of vascular stenosis in patients with carotid web is consistent with the results of CTA examination.
