While successful coronary vein imaging approaches using magnetization transfer contrast have been reported at 1.5 T, these techniques cannot easily be adopted at higher magnetic field strength because of specific absorption rate constraints. For these reasons, we have implemented a method that exploits T₂ shortening in deoxygenated blood. The hypothesis was tested whether this method enables contrast generation between the venous blood-pool and the surrounding structures at 3 T.
