Abstract

Objective To study the diagnostic value of susceptibility weighted imaging(SWI) in cerebral venous malformation.Methods The imaging data of the 21 patients with cerebral venous malformation were retrospectively analyzed.All of the patients had conventional MRI and SWI examination,We compared the superiority of the SWI to the others in showing the cerebral venous malformation.Results SWI showed 21 lesions,T1WI showed 17 lesions,T2WI showed 18 lesions.Conventional MRI revealed blood flow-void signal,and only showed many drain veins and some medullary veins.Dilated pulp veins and gross draining vein were all clearly shown by SWI,and typical caput medusae sign was showed.Conclusion SWI sequence has more sensitivity than conventional MRI in detecting the cerebral venous malformation.
