Abstract Abstract: Objective: To discuss the clinical application value of susceptibility weighted imaging(SWI) in diagnosing arterial thrombosis, evaluating the condition and prognosis of patients in acute cerebral infarction. Materials and Methods: Thirty-two cases of acute cerebral infarction were imaged with conventional MRI, DWI, MRA and SWI. All patients underwent MR imaging using 3.0T MRI system. Using SWI-mIP to display arterial thrombosis. Define susceptibility vessel sign(SVS) as an arterial thrombosis is positive on SWI. The relationship among SVS and infarction area, clinical scores and shot-term prognosis were calculated respectively. Result: in 32 cases, 16 cases showed SVS sign. The positive rate of SVS was 50%(16/32), consisted with the lesions region of MRA and mainly occured in proximal of middle cerebral artery. The acute infarction area with SVS positive was greater than the SVS negative, there had statistically difference(P<0.05). SVS displayed on SWI was associated with NIHSS scores, shot-term prognosis(P<0.05). Conclusion: SWI is useful for assessment in arterial thrombosis, providing objective imaging evidences for the choice of clinical treatment and the evaluation condition and prognosis of patients in acute cerebral infarction. SWI can be used routinely in patients with acute cerebral infarction.
