The authors report their experience with the combined use of digital subtraction angiography (DSA) and magnetic resonance imaging (MRI) for the stereotactic placement of intracerebral electrodes in epilepsy and for the radiosurgical treatment of otherwise inoperable arteriovenous malformations of the brain. Both imaging techniques, when used in conjunction, have been found most useful and complementary. For deep electrode placement, they permit optimal visualization of the cerebral structures to be reached by the electrode array while allowing the avoidance of vessels in the vicinity. For radiosurgery of arteriovenous malformations, DSA provides optimal visualization of the feeders and of the malformation itself, while the MRI reveals the cerebral structures to be spared by the photon beam of the linear accelerator. A discussion of their respective roles is presented, with the specific question as to whether MRI alone could be used for both procedures.
作者报告了他们联合使用数字减影血管造影（DSA）和磁共振成像（MRI）进行癫痫患者脑内电极立体定向放置以及对其他无法手术的脑动静脉畸形进行放射外科治疗的经验。已发现这两种成像技术联合使用时最为有用且相辅相成。对于深部电极放置，它们能使电极阵列到达的脑结构得到最佳可视化，同时可避免附近血管。对于动静脉畸形的放射外科治疗，DSA能提供供血血管和畸形本身的最佳可视化，而MRI则显示线性加速器光子束应避开的脑结构。文中对它们各自的作用进行了讨论，并特别探讨了仅使用MRI是否可用于这两种操作的问题。
