Abstract

The dynamics of the CSF circulation in six cases of intracranial arachnoid cysts was examined by RI cisternography suing 0.5 to 1.0 mCi of 169Yb DTPA or 50 to 100 microCi of 131I HSA injected into the lumbar subarachnoid space. Serial scintigrams were obtained with rectilineal scintillation scanner at 2, 4, 6, 24 and 48 hours after injection. The communication of the cavity of arachnoid cyst and subarachnoid space was recognized in all cases. The cysts were best visualized at 24 hours in most cases. Four patterns of the entry and stasis of RI in cysts were observed as follows, 1) rapid filling of RI into the cyst and delayed clearance, 2) both rapid filling and clearance, 3) slow filling and delayed clearance, 4) no filling.

摘要

通过向腰椎蛛网膜下腔注入0.5至1.0毫居里的169镱二乙三胺五醋酸（169Yb DTPA）或50至100微居里的131碘人血清白蛋白（131I HSA），利用放射性核素脑池造影术检查了6例颅内蛛网膜囊肿患者脑脊液循环的动力学情况。在注射后2、4、6、24和48小时，使用直线闪烁扫描仪获取系列闪烁图。在所有病例中均识别出蛛网膜囊肿腔与蛛网膜下腔之间的连通情况。在大多数病例中，囊肿在24小时时显示最佳。观察到放射性核素在囊肿内的进入和滞留情况有以下四种模式：1）放射性核素迅速充盈囊肿且清除延迟；2）充盈和清除均迅速；3）充盈缓慢且清除延迟；4）无充盈。
