摘要
目的:分析探讨应用高分辨率MRI血管壁成像技术(HRMR-VWI)诊断颈动脉闭塞的准确性。方法:本次研究对象共64例,是我院收治的疑似颈动脉闭塞患者,选取时间段为2019年6月—2020年12月。所有患者均接受HRMR-VWI诊断,对病史、实验室资料以及影像学资料进行综合判断,以此为最终的临床诊断。确诊完毕后,对颈动脉闭塞患者进行HRMR-VWI检查和常规管腔成像技术检查。观察HRMR-VWI的诊断效能以及病因类型诊断准确率。结果:64例疑似颈动脉闭塞患者,确诊患者有40例,占比62.50%,非颈动脉闭塞患者24例,占比37.50%。HRMR-VWI诊断颈动脉闭塞例数为39例,非颈动脉闭塞例数为25例,诊断灵敏度为92.50%(37/40)、特异度为91.67%(22/24),准确度为92.19%(59/64)。与常规管腔成像技术检查相比,HRMR-VWI病因类型诊断准确率高95.00%V S72.50%(χ^(2)=7.440,P<0.05)。结论:HRMR-VWI技术诊断颈动脉闭塞诊断效能良好,还可明确患者闭塞血管病因,准确性高,利于患者后续治疗。
Objective To investigate the accuracy of high resolution MRI wall imaging(HRMR-VWI)in the diagnosis of carotid artery occlusion.Methods A total of 64 patients with suspected carotid occlusion in our hospital were selected from June 2019 to December 2020.All patients received HRMR-VWI diagnosis,and the history,laboratory data and imaging data were comprehensively judged as the final clinical diagnosis.After diagnosis,the patients with carotid artery occlusion were HRMRVWI and conventional lumen imaging.Observe the diagnostic efficacy of HRMR-VWI and the diagnostic accuracy of etiological types.Results 64 patients with suspected carotid occlusion,Forty patients were diagnosed,62.50%,24 patients with non-cervical occlusion,The proportion is 37.50.HRMR-VWI diagnosis of carotid occlusion was 39,The number of non-carotid artery occlusions was 25,Diagnostic sensitivity was 92.50%(37/40),specificity was 91.67%(22/24),accuracy of 92.19%(59/64).Compared with conventional lumen imaging,The diagnostic accuracy of HRMR-VWI etiological type was 95.00%VS72.50%(χ^(2)=7.440,P<0.05).Conclusion HRMR-VWI technique has good diagnostic efficacy in the diagnosis of carotid artery occlusion,and can also clarify the etiology and accuracy of occlusion,which is beneficial to the follow-up treatment of patients.
