Abstract

With T1-weighted gradient recalled echo (GRE) MR images and flow compensation, we studied the superior sagittal sinus in 3 normal volunteers and 3 patients with sinus occlusion. In these images, sites of patency of the superior sagittal sinus were identified due to the high signal intensity of the normal sinus. Tumor invading the sinus was nearly isointense with cerebral gray matter. T1-weighted GRE imaging proves to be an effective technique to evaluate sinus blood flow.

摘要

利用T1加权梯度回波（GRE）磁共振成像和血流补偿技术，我们对3名正常志愿者和3名上矢状窦闭塞患者的上矢状窦进行了研究。在这些图像中，由于正常上矢状窦的高信号强度，可确定其通畅部位。侵犯上矢状窦的肿瘤与脑灰质几乎等信号。T1加权GRE成像被证明是评估上矢状窦血流的一种有效技术。
