MRI & MRA of Spinal Cord Arterio Venous Shunts

Stphanie Condette-Auliac¹, Anne Boulin¹, Oguzhan Coskun¹, Georges Rodesch¹

Spinal cord arterio venous shunts are rare lesions and often not well known. SCAVSs are divided into four groups depending of the localization, and the type of the shunt. The imaging findings are different for each of them. The first step in the diagnosis of vascular lesion is usually MRI and knowledge of those lesions will help us to choose the sequences and technical parameters, especially MRA in order to obtain all useful data of angio-architecture and consequences on spinal cord to properly diagnose those lesions and manage the patients. Imaging characteristics of each type of lesion will be detailed.
