摘　　要：【目的】利用磁敏感加权成像(SWI)联合弥散加权成像(DWI)技术分析急性缺血性脑卒中(AIS)的影像学特征;探讨其对AIS诊断的价值。【方法】选择2016年9月至2018年6月长沙市第四医院收治的90例AIS患者的临床资料;根据其类型将其分为心源性AIS组(n=55)和非心源性AIS组(n=35)。两组给予SWI、DWI及常规MRI检查;将两组间临床资料和影像评估结果进行对比。【结果】心源性AIS组美国国立卫生研究院卒中量表(NIHSS)评分高于非心源性AIS组;差异有统计学意义(P<0.05)。心源性AIS组与非心源性AIS组的DWI梗死灶体积和脑内微出血灶(CMB)阳性率比较;差异均无统计学意义(P>0.05)。心源性AIS组出现突出皮质静脉(PCV)、敏感性血管征(SVS)阳性率明显高于非心源性AIS组;差异有统计学意义(P<0.05)。【结论】心源性AIS患者NIHSS评分、SVS和PCV阳性率明显高于非心源性AIS患者;SWI联合DWI能为AIS患者提供丰富的诊断信息;对指导临床制定个体化治疗方案具有重要意义。【Objective】 To analyze the imaging features of Magnetic sensitivity weighted imaging (SWI) combined with diffusion-weighted imaging (DWI) for acute ischemic stroke (AIS) and to evaluate its diagnostic value.【Methods】 From September 2016 to June 2018, 90 patients with AIS were selected and divided into cardiogenic AIS group (n=55) and non-cardiogenic AIS group (n=35). SWI,DWI and conventional MRI were given to the two groups, and the clinical data and imaging evaluation results were compared between the two groups.【Results】 The (NIHSS) score of stroke scale in the cardiogenic AIS group was significantly higher than that in the non-cardiogenic AIS group (P<0.05). There was no significant difference in the positive rate in DWI infarct volume and Intracerebral microhemorrhage focus (CMB) between the cardiogenic AIS group and the non-cardiogenic AIS group (P>0.05). The positive rate of protrusion cortical vein (PCV) and sensitive vascular sign (SVS) in the cardiac AIS group was significantly higher than that in the non-cardiogenic AIS group (P<0.05).【Conclusions】The positive rates of NIHSS, SVS and PCV in cardiogenic AIS patients are significantly higher than those in non-cardiogenic AIS patients. SWI combined with DWI can provide rich diagnostic information for AIS patients. It is of great significance to guide the clinical design of individualized treatment.
