摘　　要：目的:探讨磁敏感加权成像(SWI)的磁敏感血管征(SVS)结合磁共振血管成像(MRA)对急性脑梗死患者的诊断及治疗的价值。方法:回顾性分析2022年1月—2023年4月在北大医疗鲁中医院经临床及影像检查确诊为急性脑梗死的60例患者,观察MRA上表现为责任血管狭窄或闭塞的部位,以及对应SWI序列上SVS征的位置,并研究两者的一致性。结果:MRA发现动脉狭窄或闭塞41例(68.3%),阴性19例(31.7%),SVS征阳性有26例(43.3%),SWI与MRA对发现血栓和狭窄的一致性中等(Kappa值=0.523,P<0.05)。结论:当MRA发现血管存在狭窄或闭塞时,结合血管SWI的SVS征,能敏感地发现管腔内的红色血栓,可使急性脑梗死患者的诊断准确率得到提升,这对患者及时有效治疗起到了积极作用。Objective To investigate the significance of susceptibility vessel sign(SVS)on susceptibility-weighted imaging(SWI)combined with magnetic resonance angiography(MRA)in the diagnosis and treatment of patients with acute cerebral infarction.Methods A retrospective analysis was conducted on the 60 patients who were diagnosed acute cerebral infarction through clinical and imaging examinations from January 2022 to April 2023 in PKUCare Luzhong Hospital,to observe and record the stenosis or occlusion vascular of MRA and the position of SVS sign on SWI,and the consistency between the two was compared.Results 41 cases(68.3%)were found with stenosis or occlusion vascular on MRA,19 cases(31.7%)were negative on MRA.26 cases(43.3%)were positive for SVS.The consistency of thrombosis and stenosis was medium(Kappa value=0.523).Conclusion Through stenosis or occlusion vascular on MRA and SVS sign on SWI,the diagnostic accuracy of patients with acute cerebral infarction can be improved,and the more sensitive detection of red thrombus in the arterial lumen,which has a very positive effect on the timely and effective treatment of patients.
