Inherent soft-tissue contrast and multi-planar imaging of MRI without ionizing radiation makes it appealing for guidance of traditional and complex cardiovascular access. In this work, we have utilized real-time MRI to guide peripheral vascular access in addition to more precise targeting of direct cardiac access to the right ventricle in swine. MR imaging with compatible devices provides valuable anatomical information to the operator and enables trajectory planning and procedure monitoring to ensure a safe and efficient entry to the heart and vasculature.
