Abstract

Objective:To investigate the value of conventional MRI, MRA and MRV for diagnosis of cerebral venous sinus thrombosis (CVST).Metheds:The clinical and imaging data were retrospectively analyzed in 10 cases of proved CVST.Conventional MRI,MRA and MRV were performed in all 10 cases,of which 9 cases were accepted Gd-DTPA injection.Result:There were abnormal signals in brain tissue in all 10 cases,and only 1 case had normal T2WI signal. Abnormal venous enhancement was found on contrast enhancement in all 9 cases.MRA showed not only the artery,but also thrombosed venous sinuses in 5 cases.MRV showed loss of singals of thrombosed venous sinuses.Conclusion:Conventional MRI combined with MRA and MRV are effective and noninvasive methods in the diagnosis of cerebral venous sinus thrombosis.
