Comparison of imaging modalities for the accurate delineation of arteriovenous malformation, with reference to stereotactic radiosurgery

Conclusion: The shift of centers between each modality is not negligible. Considering no significant difference between VDSA and VMRA, but inadequate coverage of the VDSA by VMRA, it is reasonable to consider that the target on MRA might include the feeding artery and draining vein and possibly miss a portion of the nidus.
