In order to study the role of Gd-DTPA-enhanced MR imaging in dural sinus thrombosis, precontrast and postcontrast imaging using Gd-DTPA in three patients with clinically unsuspected dural sinus thrombosis was reviewed. Comparisons were made with cranial CT scanning and cerebral angiography. Compared to CT, the postcontrast T1-weighted images more clearly revealed thrombus in the dural sinuses as a nonenhanced central area of intermediate intensity (but not flow void) surrounded by an enhanced rim. MR imaging also demonstrated secondary changes, including the presence of collateral venous channels and venous infarction.
为研究钆喷酸葡胺增强磁共振成像（Gd-DTPA-enhanced MR imaging）在硬脑膜窦血栓形成中的作用，回顾了3例临床未怀疑硬脑膜窦血栓形成患者使用钆喷酸葡胺进行的对比前和对比后成像。并与头颅CT扫描和脑血管造影进行了比较。与CT相比，对比后T1加权图像更清晰地显示硬脑膜窦内血栓为中等强度的非强化中央区（但不是流空），周围有强化边缘。磁共振成像还显示了继发性改变，包括侧支静脉通道的存在和静脉梗死。
