Accurate quantification of myocardial motion requires high spatial and temporal resolution velocity-encoded MRI. Acceleration of the data acquisition appears mandatory for enabling three-dimensional coverage of the whole heart. It is the objective of this study to compare the impact of acquisition acceleration by means of SENSE and kt-BLAST on the velocity-time curves. The comparison is performed in a beating heart phantom ensuring highly reproducible motion pattern. The results indicate a superior performance of SENSE for preservation of the motion curves compared to kt-BLAST.
