Stenosis Detection with MR Angiography and Digital Subtraction Angiography in Dysfunctional Hemodialysis Access Fistulas and Grafts

Abstract

MR angiography depicts stenoses in dysfunctional hemodialysis accesses but has limited clinical value as result of current inability to perform MR-guided access interventions after stenosis detection. MR of dysfunctional access should be considered only if nondiagnostic vascular segment is present at DSA.
