摘要
目的:分析急性期缺血性脑卒中(AIS)患者经磁敏感加权成像(SWI)结合动脉自旋标记成像(ASL)的诊断效用.方法:选取2020年7月至2021年7月于重庆医科大学附属永川医院就诊的AIS患者50例,用3.0T MRI进行扫描,扫描序列包括FLAIR、DWI、3D-TOF-MRA、3D-ASL和SWI,分别评估患者脑梗的灌注状态、梗死核心区周围引流静脉、侧支代偿情况、是否有出血转化以及患者的预后水平.结果:梗死核心区周围引流静脉的分级与患者NIHSS评分呈显著相关(r=0.869,P＜0.05);梗死核心区周围引流静脉的分级与患者的预后呈显著相关(r=0.825,P＜0.05);梗死核心区灌注状态与是否出现出血转化呈显著相关(r=0.873,P＜0.05);侧支循环代偿状态与患者预后呈显著相关(r=0.883,P＜0.05).结论:SWI联合ASL可以对AIS患者梗死核心区周围的血流动力学情况给予准确提示,并且该技术还可以准确评估AIS患者的预后,对临床诊断以及治疗方案的选择均有重要价值.
Abstract
Objective To analyze the diagnostic utility of combining susceptibility-weighted imaging(SWI)with arterial spin labeling(ASL)in patients with acute ischemic stroke(AIS).Methods Fifty AIS patients who admitted to Yongchuan Hospital,Chongqing Medical University from July 2020 to July 2021 were selected.Scans were performed using a 3.0T MRI scanner,including sequences such as FLAIR,DWI,3D-TOF-MRA,3D-ASL,and SWI.The perfusion status of the infarction core,the grading of draining veins around the infarction core,compensation by collateral circulation,the occurrence of hemorrhagic transformation,and prognosis were assessed.Results The grading of draining veins around the infarction core was significantly correlated with NIHSS scores(r=0.869,P＜0.05)and prognosis(r=0.825,P＜0.05).In addition,significant correlations were found between the perfusion status of the infarction core and the occurrence of hemorrhagic transformation(r=0.873,P＜0.05),compensation by collateral circulation and prognosis(r=0.883,P＜0.05).Conclusion The combination of SWI and ASL provides accurate indications of the hemodynamic conditions around the infarction core in AIS patients,and it can accurately assess the prognosis of AIS patients,contributing valuable information for clinical diagnosis and the selection of treatment strategies.
