title: Response of arteriovenous malformations to gamma knife therapy evaluated with pulsed arterial spin-labeling MRI perfusion.
abstract: OBJECTIVE
  The goal of this study was to use pulsed arterial spin-labeling (PASL) MRI to evaluate the effect of gamma knife treatment on arteriovenous malformation (AVM) blood flow by measuring perfusion of the AVM nidus and nearby vascular territories.
  
  
  CONCLUSIONS
  PASL can show and quantify the steal phenomena and the relative flow rates within the AVM nidus and may be used to follow AVM perfusion over time to assess treatment efficacy.
