IA MR perfusion techniques appear to be a useful adjunct to DSA in determining tumor vascularity and the source of that blood supply during DSA guided preoperative embolization procedures. IA MR perfusion techniques appear to be more sensitive than DSA in detecting residual vascularized tumor. Further correlations with intraoperative observations and pathologic specimens are warranted to better assess the overall sensitivity and specificity of IA MR perfusion and to determine its overall utility in comparison to DSA and IV perfusion methods.
