The diagnostic value of scintigraphy with technetium-99m labeled red blood cells (Tc-RBC) was assessed in 19 patients with clinical suggestion of superior sagittal sinus thrombosis (SSST). Comparison of Tc-RBC static images with dynamic flow studies in the brain showed a sensitivity of 100%, specificity of 86%, and accuracy of 94% for static studies and values of 87%, 20%, and 61%, respectively, for the flow studies. Tc-RBC scintigraphy enables direct visualization of the integrity of the superior sagittal sinus, whereas CT scanning shows various but nonspecific changes in the brain associated with SSST. Single-photon emission CT study using Tc-RBC, performed in six patients, appears to have potential in the diagnosis of SSST, allowing separation of vascular structures that are superimposed on the superior sagittal sinus in planar scintigraphy study.
对19例临床提示上矢状窦血栓形成（SSST）的患者评估了锝-99m标记红细胞（Tc-RBC）闪烁扫描术的诊断价值。脑Tc-RBC静态图像与动态血流研究的比较显示，静态研究的敏感性为100%，特异性为86%，准确性为94%，而血流研究的值分别为87%、20%和61%。Tc-RBC闪烁扫描术能够直接观察上矢状窦的完整性，而CT扫描显示与SSST相关的脑内各种非特异性改变。对6例患者进行的使用Tc-RBC的单光子发射CT研究在SSST诊断中似乎具有潜力，可在平面闪烁扫描研究中分离叠加在上矢状窦上的血管结构。
