Abstract
Objective To explore the application value of Susceptibility Weighted Imaging (SWI) in the diagnosis of brain arteriovenous malformation (BAVM) with concealed regional micro hemorrhage and to predict factor risk of BAVM rupture hemorrhage.Methods This study retrospectively analyzed 24 cases of patients with BAVM that were confirmed by pathology after surgery. MRI and SWI scans were used to reconstruct the BAVM imaging with minimal intensity projection.Results 11 cases were diagnosed with old hemorrhage accompanied by concealed regional micro hemorrhage, and 15 cases had symptomatic intracranial hemorrhage, chi square test indicated that diagnostic accuracy was 73.3%. In the multivariable logic regression analysis model, old hemorrhage and concealed regional micro hemorrhage are closely related (OR=8.81, 95%CI: 0.75~102.92,P=0.083, <0.1); deep venous drainage and concealed regional micro hemorrhage of old hemorrhagic are closely related (OR=10.88, 95%CI: 0.86~136.96,P=0.065, <0.1).Conclusion Diagnosing concealed regional micro hemorrhage with SWI can evaluate risk of BAVM rupture.关键词
