MR-guided cardiovascular interventions do not use ionizing radiation, provide excellent soft tissue contrast, and enable functional measurements. The feasibility of MR-guided percutaneous coronary intervention has been demonstrated in animal trials using metallic stents. Recently, bio-resorbable vascular scaffolds have been introduced for stenting of coronary arteries. These scaffolds enable artifact-free MR imaging of the coronary artery segment that the result of the intervention can be readily assessed via MR imaging. We show the first fully MR-guided PCI with a bioresorbable scaffold in the LCA of a pig at 3T using dedicated active guiding catheters, an MR-safe guidewire and BVS delivery system.
