Short scan times for velocity-encoded black-blood functional cardiac imaging with good spatial resolution are desirable since patient compliance prohibits excessive scan times. Applying kt-Blast shortens the scan duration and therefore allows acquiring data with better spatial resolution in the same time. An analysis of the myocardial motion was performed and the characteristic velocities determined with and without kt-Blast were compared revealing an agreement of results. Kt-Blast can therefore be used to mitigate the problem of restricted spatial resolution resulting from a limited scan time.
