The medulla was studied in cadavers and in 100 patients both with and without the intrathecal administration of contrast material. The computed tomographic (CT) anatomy was correlated with the appearance of anatomic dissections. The pyramids, olives, and inferior cerebellar peduncles produced characteristic contours on cross sections of the medulla. The hypoglossal nerve by its location and course in the medullary cistern could be distinguished from the glossopharyngeal, vagal, and spinal accessory nerves. For optimal evaluation of the medulla, intrathecal administration of metrizamide and 5- and/or 1.5-mm-thick axial and coronal sections are recommended.
对尸体以及100例接受和未接受鞘内注射造影剂的患者的延髓进行了研究。计算机断层扫描（CT）解剖结构与解剖解剖的外观相关。锥体、橄榄和小脑下脚在延髓横断面上产生特征性轮廓。舌下神经通过其在延髓池中的位置和走行可与舌咽神经、迷走神经和副神经相区分。为了对延髓进行最佳评估，建议鞘内注射甲泛葡胺，并采用5毫米和/或1.5毫米厚的轴向和冠状面切片。
