Abstract：【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.
