To review imaging features and the spectrum of dural arteriovenous fistulas of the spine by MR and intraarterial angiography. To optimize technical parameters to establish an early, accurate and reliable diagnosis.  

We retrospectively reviewed 23 patients with dural arteriovenous fistulas treated in our center between january 2010 and january 2014. All patients underwent MR, because of different clinical conditions and AVF was suspected. MR proved to be good in guiding the angiographic study. Procedure was shorter, less contrast media was administrated, less radiation dose was necessary and a lowe rate of complications was noticed in these patients if compared with those without a previous MR study. Imaging features of fistulas were similar in MR and DSA in most cases. MR is more available, less invasive and cheaper than angiography. DSA confirms the diagnosis and allows to perform endovascular treatment.
