Abstract:Objective: To evaluate the value of MRI, 3D-CE-MRA in the diagnosis of cerebral venous sinus thrombosis. Methods: Twenty-two patients with cerebral venous sinus thrombosis were examined with spin-echo MR imaging and MR venography. Various imaging features were analysed. Result: Ten cases with secondary intraparenchymal abnormalities were shown by MRI(SE sequence), 13 cases with thrombosis in superior sagittal venous sinus, transverse sinus and straight sinus were also shown, MRV examination demonstrated superior sagittal sinus thrombosis in 6 cases, inferior sagittal sinus thrombosis in 1 case, superior sagittal sinus thrombosis complicated with straight sinus thrombosis in 2 cases. Superior sagittal sinus complicated with transverse sinus, sigmoid sinus thrombosis in 3 cases, transverse sinus complicated with sigmoid sinus thrombosis in 3 cases, cavernous sinus thrombosis in 1 case, vein of galen and internal cerebral venous thrombosis in 1 case. Superior cerebral vein and anastomatic venous thrombosis in 1 case. All the cases were proved by DSA. Conclusion: Combination of MRI and 3D-CE-MRV can show CVT accurately and is the best methods in demonstrating CVT.
