Low-Dose Contrast-Enhanced MR Angiography

Abstract

Today, three-dimensional contrast-enhanced magnetic resonance angiography (CE-MRA) is a widely accepted and powerful diagnostic tool for assessment of almost all vascular territories. Its noninvasive nature and flexibility make CE-MRA an appealing alternative to digital subtraction angiography (DSA) or computed tomography angiography (CTA). In addition, compared to the iodinated contrast agents used in CTA and DSA, gadolinium-based contrast agents have long enjoyed an excellent safety record. In the past, there has been little motivation for, or emphasis on, dose reduction strategies.
