MR-guided cardiovascular interventions

Abstract

In addition to the diagnostic evaluation of the peripheral and coronary arteries, magnetic resonance angiography (MRA) is also an appealing method for MR-guided interventions, because there are variable advantages using MR when compared to X-ray guidance: MRA displays the vessel lumen without the need of contrast agents, it does not utilize ionizing radiation and it offers a superior soft tissue contrast. The tomogaphic nature of MR imaging enables vessel display without overlay of other structures. In addition to the vessel lumen, the vessel wall can also be assessed which allows for soft plaque visualization in patients without lumen narrowing [84, 96]. This may be helpful for guidance of vascular interventions. Finally, functional studies including flow quantification can be performed.
