摘要
目的:探讨运用三维对比增强MR血管造影技术(3D-CE-MRA)的MRV在脑静脉血栓(CVT)的各种影像学诊断中的价值。方法:回顾22例经MRI、MRV及DSA检查CVT的病例,重点观察分析各种影像学表现。结果:MRI(SE序列)检查共显示脑实质继发改变10例;显示上矢状窦、横窦及直窦血栓共13例;MRV检查显示上矢状窦血栓6例;下矢状窦血栓1例;上矢状窦合并直窦2例;上矢状窦合并横窦、乙状窦3例;横窦合并乙状窦血栓3例;海绵窦血栓1例;大脑大静脉及大脑内静脉血栓1例;大脑上静脉及吻合静脉血栓1例。全部病例均经DSA检查证实。结论:MRI与3D-CE-MRA成像技术的MRV相结合可以全面、准确地显示CVT,为CVT检出的最佳方法。
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.
