MRA of the Aorta and Peripheral Arteries
It can be argued that magnetic resonance angiography of the aorta and peripheral vessels has undergone more dramatic changes over the last couple decades than any other form of cardiovascular magnetic resonance imaging. The first useful clinical applications primarily used two-dimensional time-of-flight technology. However, in the mid-1990s, this approach was replaced to a large degree by contrast-enhanced techniques using conventional agents in dynamic, multiphase mode. Blood pool agents have also been developed for use in magnetic resonance angiography, but their precise role remains to be determined. Given the risks of gadolinium contrast in patients with renal failure, which is not an unusual concomitant in patients undergoing vascular evaluation, there has been a recent resurgence in interest in the use of non-contrast magnetic resonance angiographic approaches.
