Since the introduction of CT, the assessment of ventricular enlargement and follow-up examinations after shunt surgery have become easier. By means of CT coronary and sagittal reconstructions as well as nuclearmagnetic resonance, the pathologic-anatomic changes in malformations with Arnold-Chiari II deformity and Dandy-Walker syndrome are clearly demonstrated. With nuclear magnetic resonance the morphology of structures in the posterior cranial fossa are demonstrated three-dimensionally, and in comparison with CT the method has the advantage that it involves no exposure to radiation. On the other hand, dynamic conditions of the CSF circulation can be evaluated better on the computerized tomogram following intrathecal injection of contrast medium. On the basis of our experience we believe that the different methods are complementary and can often be combined when planning surgery.
自从CT问世以来，脑室扩大的评估以及分流手术后的随访检查变得更加容易。通过CT冠状位和矢状位重建以及核磁共振，可以清晰地显示出伴有Arnold-Chiari II畸形和Dandy-Walker综合征的畸形病变中的病理解剖变化。利用核磁共振可以三维显示后颅窝结构的形态，与CT相比，该方法的优点是无需暴露于辐射。另一方面，在鞘内注射造影剂后的计算机断层扫描上，可以更好地评估脑脊液循环的动态情况。根据我们的经验，我们认为不同的方法是互补的，在规划手术时常常可以结合使用。
