High field magnetic resonance (MR) imaging enables us to demonstrate the evolution of cerebral venous thrombosis. Initially, absence of a flow void and collateral venous channels are seen on T1 weighted images (WI). On T2WI thrombus appears hypointense. Hyperintensity is noted in an intermediate stage of thrombosis first on T1WI and later on T2WI. In the late stages recanalization of the vessel occurs with reappearance of the flow void. These findings are specific for venous thrombosis. High field MR may be the imaging modality of choice in the diagnosis of venous thrombosis.
高场强磁共振成像能够让我们展示脑静脉血栓形成的演变过程。最初，在T1加权像（WI）上可见血流空信号缺失以及侧支静脉通道。在T2WI上血栓呈低信号。在血栓形成的中间阶段，首先在T1WI上，随后在T2WI上可见高信号。在晚期，血管再通，血流空信号再次出现。这些表现对静脉血栓形成具有特异性。高场强磁共振可能是诊断静脉血栓形成的首选成像方式。
