Techniques and applications for contrast-enhanced magnetic resonance angiography (CE-MRA) have developed rapidly in recent years, due largely to advances in hard- and software design. The advent of innovative new contrast agents with properties distinct from those of the traditional, extracellular gadolinium agents promises to further expand the clinical applicability of CE-MRA, making this the modality of choice for diagnostic imaging of the vasculature. With few exceptions, most of the commercially available contrast agents are not approved directly for CE-MRA [1, 2]. The present review summarizes the properties and imaging applications of currently available contrast agents which are in routine use in CE-MRA. Described also are those agents in clinical development which may one day find utility in CE-MRA.
