Intra- and inter-observer variability in the angiographic delineation of brain arterio-venous malformations (AVMs)
Abstract
The purpose of this study is to determine the intra- and inter-observer variability in the manual delineation of the boundaries of brain arterio-venous malformations (AVMs) on digital subtracted angiograms. Such delineation is used to define the target volume in stereotactic radiotherapy.
