摘要
目的通过与数字减影血管造影(DSA)比较,评价三维磁共振管壁成像(3D-MR-VWI)技术诊断颈动脉闭塞形态学特征的可行性。资料与方法纳入经超声诊断为颅外段颈动脉闭塞(CAO),并于1周内完成3D-MR-VWI和DSA检查的124例患者。评价3D-MR-VWI与DSA在诊断CAO类型和闭塞发生部位的一致性。结果3D-MR-VWI对于颈动脉完全闭塞及闭塞起始部位的诊断与DSA结果均有较高的一致性(Cohen’s κ=0.85,95%CI 0.71~0.94;Cohen’s κ=0.85,95%CI 0.71~0.97)。3DMR-VWI诊断颈动脉完全闭塞的敏感度为97.0%,特异度为86.7%,准确率为94.6%。结论3D-MR-VWI能够准确诊断CAO并判定闭塞的形态学特征,可为临床诊治颈动脉闭塞性病变提供参考。
Purpose To evaluate the feasibility of three-dimensional magnetic resonance vessel wall imaging(3D-MR-VWI)in the diagnosis of carotid artery occlusion by comparison with digital subtraction angiography(DSA).Materials and Methods 124 patients diagnosed as extracranial carotid artery occlusion(CAO)by ultrasound,and completed 3D-MR-VWI and DSA within 1 week were enrolled in this study.The consistency of 3D-MR-VWI and DSA in the diagnosis of CAO type and the location of occlusion was analyzed.Results The diagnosis of complete carotid occlusion and initial site of occlusion by 3D-MR-VWI was highly consistent with DSA results(Cohen's κ=0.85,95%CI 0.71-0.94;Cohen's κ=0.85,95%CI 0.71-0.97).The sensitivity,specificity and accuracy rate of 3D-MR-VWI in the diagnosis of carotid artery occlusion was 97.0%,86.7%and 94.6%,respectively.Conclusion 3D-MR-VWI can accurately diagnose CAO and determine the morphological characteristics of occlusion,and can provide a reference for clinical diagnosis and treatment of carotid occlusive disease.
