Comparison of Two Blood Pool Contrast Agents for 0.5-T MR Angiography: Experimental Study in Rabbits

Abstract

Both blood pool agents were found to be promising contrast agents for 0.5-T MR angiography; however, their clinical applicability warrants further investigation. The gadolinium-based agent had several advantages over the iron oxide compound, including less T2* dephasing, lack of susceptibility artifacts, and fast renal elimination.
