[Magnetic resonance imaging-guided endovascular interventions].

Historically, the combination of relatively long imaging times and restricted patient access has made MRI-guided intervention an impractical technique. Recent developments in MR hardware, pulse sequence improvements that have allowed the development of rapid imaging, and the availability of instruments that can be used under MR guidance have helped to overcome many of the disadvantages of MRI. Parallel to the development of MRI, image-guided percutaneous and endovascular interventions are becoming increasingly complex and require progressively more sophisticated imaging techniques to guide and control such interventions. These initially parallel trends have converged in the last couple of years. The ability of MRI to provide both unprecedented morphology and functional information has created a growing interest in both percutaneous and endovascular MRI-guided interventions. The goal of this review is to describe the technical prerequisites for MR-guided endovascular interventions, to discuss experimental and clinical applications, and to explain safety aspects of this technique.
