摘要
目的:分析不同磁共振成像(MRI)技术在急性脑梗死动脉血栓患者中的诊断及预后的应用价值。方法:选取医院收治的46例急性脑梗死动脉血栓患者病例资料,依据血栓负荷评分(CBS)将其分为≤5分组(8例)、6~9分组(18例)和10分组(20例)。所有患者均行常规MRI扫描、磁敏感加权成像(SWI)及弥散加权成像(DWI),对比常规MRI的SWI、DWI序列下急性脑梗死动脉血栓的诊出率,对比不同CBS得分患者美国国立卫生研究院卒中量表(NIHSS)评分差异,并随访不同CBS得分患者的预后情况。结果:MRI共检出动脉血栓37例,SWI检出43例,DWI检出38例。根据MRI、SWI及DWI的影像学表现分析CBS评分,单因素方差分析中CBS得分≤5分组、6~9分组和10分组的NIHSS评分比较,差异具有统计学意义(F=36.682,P<0.05);其中≤5分组患者的NIHSS评分显著高于6~9分组和10分组;6~9分组显著高于10分组,差异具有统计学意义(t=3.845,t=8.145,t=5.459;P<0.05)。CBS与NIHSS评分经Spearman相关性分析显示,两者呈负相关(r=-0.700,P<0.001)。随访结果中CBS≤5分组、6~9分组预后显著差于10分组,差异具有统计学意义(χ^(2)=11.663,P<0.05)。结论:SWI技术对急性脑梗死动脉血栓诊断价值高于常规MRI与DWI检查,但对预后的评估需要临床中根据患者其他技术表现进行综合判断。
Objective:To analyze the application value of different magnetic resonance imaging(MRI)techniques in the diagnosis and prognosis of patients with acute cerebral infarction of arterial thrombosis.Methods:The data of 46 patients with acute cerebral infarction of arterial thrombosis who admitted to hospital were selected and were divided into≤5 scores group,6~9 scores group and 10 scores groups according to clot burden score(CBS).Routine MRI scanning,magnetic sensitivity weighted imaging(SWI)and diffusion weighted imaging(DWI)were performed in all patients to compare the confirmed rates of acute cerebral infarction of arterial thrombosis of routine MRI,SWI and DWI sequence.The difference of the scores of the National Institutes of Health Stroke Scale(NIHSS)in patients with different CBS scores were further compared,and the prognoses of patients with different CBS scores were followed up.Results:In 46 patients,37 cases with arterial thrombosis were confirmed by MRI,and 43 cases with that were confirmed by SWI,and 38 cases with that were confirmed by DWI.According to MRI,SWI and DWI imaging performance,CBS scores of them were analyzed.The results of one-way analysis of variance indicated that the difference of NIHSS scores among≤5 scores group,6-9 scores group and 10 scores group was significant(F=36.682,P<0.05).The NIHSS score of≤5 scores group was significantly higher than that of 6-9 scores group and 10 scores group,respectively,and that of 6-9 scores group was significant higher than that of 10 scores group(t=3.845,t=8.145,t=5.459,P<0.05).The results of spearman correlation analysis showed that CBS scores were negative correlation with NIHSS scores(r=-0.700,P<0.001).According to the follow-up results,the prognoses of CBS≤5 scores group and 6-9 scores group were significantly worse than that of 10 scores group(χ^(2)=11.663,P<0.05),respectively.Conclusion:The diagnostic value of SWI is higher than that both of conventional MRI and DWI for acute cerebral infarction of arterial thrombosis.But the assessment o
