The application of intravenous, intrathecal, and inhalation enhancement techniques to the CT evaluation of the nonhuman primate (Papio cynocephalus/anubis) is described. The falx cerebri cortical vasculature, vein of Galen, straight sinus and tentorium cerebelli were defined with intravenous enhancement. Intrathecal CT enhancement with air was limited by distortion in cerebrospinal fluid spaces. Intrathecal CT enhancement using a low dose of metrizamide accurately delineated the subarachnoid spaces and the brain substance they surrounded with minimal morbidity. Symmetrical brain enhancement (perfusion) was prominent following inhalation CT enhancement; the degree of enhancement correlated with the estimated xenon concentration in the bloodstream. In addition, by performing repeated CT scans during the clearance of xenon from the brain, an approximate analysis of regional cerebral blood flow was obtained.
描述了静脉内、鞘内和吸入增强技术在非人灵长类动物（狒狒/埃及狒狒）CT评估中的应用。大脑镰皮质血管、大脑大静脉、直窦和小脑幕通过静脉内增强得以显示。鞘内空气增强CT受脑脊液间隙变形的限制。使用低剂量甲泛葡胺进行鞘内CT增强能准确勾勒出蛛网膜下腔及其所包围的脑实质，且发病率极低。吸入CT增强后，对称的脑增强（灌注）很明显；增强程度与血流中估计的氙浓度相关。此外，通过在氙从脑中清除过程中进行重复CT扫描，可获得局部脑血流的近似分析。
