E-120 The utility of MRI and MRA in the follow-up evaluation of treated dural arteriovenous fistulas: a preliminary analysis

ConclusionMRI/MRA evidence of residual or recurrent dAVF is not reliably found between two neuroradiologists or as compared to angiographic results. Catheter angiogram remains the standard for follow-up of treated dAVF.ReferencesNewton TH, Cronqvist S. Involvement of dural arteries in intracranial arteriovenous malformations.
