目的：探讨硬膜窦血栓形成的ＭＲＩ表现。方法：６例硬膜窦血栓形成，均做了ＭＲＩ检查，其中２例用了ＳＴＩＲ，１例用了ＦＬＡＩＲ序列，３例作了增强检查（Ｇｄ－ＤＴＰＡ），５例作了ＭＲＶ。结果：右横窦栓塞２例，左横窦１例，上矢状窦３例，脑肿胀５例，静脉性脑栓塞２例，脑血肿１例。增强检查，脑皮质及皮质静脉增强１例。结论：ＭＲＩ对硬膜窦血栓形成的诊断有独特的价值。硬膜窦流空信号消失和硬膜窦狭窄、闭塞是直接征像。脑肿胀、静脉性脑梗塞、脑血肿是间接征像
Objective: To investigate MRI findings of dural sinus thrombosis. Methods: Six cases of dural sinus thrombosis were examined by MRI. Two cases had STIR, one case had FLAIR sequence, three cases had enhanced examination (Gd-DTPA) and five cases had MRV. Results: Right transverse sinus embolism in 2 cases, left transverse sinus in 1 case, superior sagittal sinus in 3 cases, brain swelling in 5 cases, venous cerebral embolism in 2 cases and cerebral hematoma in 1 case. Enhanced examination, cerebral cortex and cortical vein enhancement in 1 case. Conclusion: MRI has a unique value in the diagnosis of dural sinus thrombosis. Dural sinus flow empty signal disappears and dural sinus stricture, occlusion is a direct sign. Brain swelling, venous cerebral infarction, cerebral hematoma is an indirect sign
