The pons is covered by a rich venous network offering numerous vascular landmarks in MRI and during surgery. We present an original study of the veins as they appear on MR multiplanar scans after gadolinium IV injection. This prospective study is based on 40 consecutive patients with normal posterior fossa structures. One of the major venous collectors follows the pons: the superior petrosal v. was identified on MRI in 95% of our cases. Its hooklike extremity drains into the superior petrosal sinus. The inferior petrosal v. was never identifiable. The superficial pontine venous network are identified in 72.5% of cases in the axial plane and were organised in longitudinal and transverse collectors, whose MR aspects are presented here.
脑桥被丰富的静脉网络覆盖，在磁共振成像（MRI）及手术过程中提供了众多血管标志。我们对静脉注射钆后在MR多平面扫描上显示的静脉进行了一项原创性研究。这项前瞻性研究基于40例后颅窝结构正常的连续患者。其中一条主要的静脉收集器沿脑桥走行：在我们95%的病例中，岩上静脉在MRI上可被识别。其钩状末端汇入岩上窦。岩下静脉从未被识别。脑桥浅静脉网络在轴位平面上72.5%的病例中可被识别，并由纵向和横向收集器组成，此处展示了它们的MR表现。
