Delineation of brain AVMs on MR-Angiography for the purpose of stereotactic radiosurgery

Conclusions: Brain arteriovenous malformations delineated on MRA are larger and more randomly displaced. However, for bAVMs ≤3 mL, the difference in volume of normal brain tissue within the high-dose region does not seem to be clinically relevant. Therefore, MRA-images might be used as the sole imaging modality for the radiosurgical treatment of bAVMs ≤3 mL when the bAVM is located in a noneloquent position.
