MR molecular imaging of low doses of tracer material often requires long scan times and makes motion compensation strategies desirable. 3D radial imaging with golden section profile interleaving allows auto-navigated motion compensation. Here, it is applied to simultaneous 19F/1H imaging of the aorta of atherosclerotic rabbits after systemic administration of 19F-based angiogenesis-targeted nanoparticles. Tracking of respiratory motion is
