Magnetic resonance imaging (MRI) has progressively become the major or even the only imaging procedure for displaying the vascular relationships of the brainstem in the context of infra-tentorial lesions. In order to assess the MR sectional anatomy of the bulbar vv. 40 normal patients were examined in the MR axial, frontal and sagittal planes after gadolinium i.v. injection. The bulbar venous networks were inconstantly visualised: anterior vv. (16%). posterior (3%), lateral (8%). The vein of the lateral recess of the fourth ventricle was constant in the three planes; the inferior petrosal sinus could be seen in 82% of cases. Their relation with the posterior fossa structures are emphasised and discussed.
磁共振成像(MRI)已逐渐成为在幕下病变背景下显示脑干血管关系的主要甚至唯一的成像检查方法。为了评估延髓静脉的磁共振断层解剖,对40例正常患者静脉注射钆对比剂后,在磁共振轴位、冠状位和矢状位平面进行了检查。延髓静脉网络显示情况不一:前静脉(16%)、后静脉(3%)、外侧静脉(8%)。第四脑室外侧隐窝静脉在三个平面上均恒定可见;82%的病例可见岩下窦。文中着重强调并讨论了它们与后颅窝结构的关系。
