Abstract

Objective:To study the diagnostic value of MRI and MR venography(MRV)in cerebral venous sinus thrombosis(CVST).Methods:MR findings of 14 cases of dural sinus thrombosis diagnosed by clinic and imaging were rewiewed retrospectively.All cases were underwent non-enhanced MRI,enhanced MRI and MR venography.All cases were performed CT,additionaly 1 patients was underwent DSA.Results:CVST involved superior sagittal sinus in 4 cases,transverse sinus 6 cases,sigmoid sinus 4 cases,Direct signs and indirect of CVST could be displayed by MRI,MR venography(MRV)displayed the loss of the normal flow signal,as nonvisulization or the filling defect sign in the involved cerebral venous sinuses.Conclusion:Early MRI combined with MRV has shown significant diagnostic value in the diagnosis of cerebral venous sinus thrombosis.
