The evaluation of MR localization for intracranial arteriovenous malformation treated with gamma knife

摘要

Conclusion MR localization for AVM treated with gamma knife is reliable and effective. Objective To evaluate the image quality, treat- ment effectiveness and complications of intracranial arteriovenous malformation (AVM) treated with gamma Knife by MR localization. Methods According to Spetzler-Martin grading System, 73 intracranial AVMs were classified and treat- ed with gamma knife by MR localization. The follow-up period was 6 to 34 months. The quality f MR localiza- tion image, the changes of AVM nidi after treatment were analyzed.
