Abstract：Objective: To investigate the value of high signal vascular sign(HVS) at fluid attenuated inversion recovery imaging(FLAIR) and susceptibility weighted imaging(SWI) in 3.0T magnetic resonance for acute ischemic stroke(AIS). Methods: Sixty-two patients of AIS(<72 h) were underwent MRI. We studied the correlation between proximal HVS of AIS, susceptibility vessel sign(SVS) and distal HVS, dilation of vessels around pia mater combined with FLAIR and SWI. Results: There are 39 cases(62.9%) with proximal HVS of middle cerebral artery(MCA), 51 cases(82.2%) with distal HVS, 53 cases(85.5%) with SVS and 49 cases(79.0%) with dilation of vessels around pia mater. It has correlation between HVS at FLAIR and SVS at SWI of the offending vessel(χ2=8.255, P=0.004). There was consistency between distal HVS of MCA and vessels of pia mater around lesions(χ2=0.207, P=0.649>0.05). Conclusion: There are consistency between SVS of MCA and approximal HVS of offending vessels, distal HVS of MCA and vessels of pia mater around lesions. The detection rate of MCA thrombus at SWI is higher than FLAIR. It is very important to optimize the exam process, make the correct treatment plan and prognosis.
