Spatial encoding using radiofrequency coils can provide extremely fast imaging speeds as the localization is not the result of a time integral of a gradient pulse. In this abstract the combination of Single Echo Acquisition (SEA) imaging and an echo-planar readout is demonstrated, resulting in 64 x 64 images obtained at frame rates exceeding 1000 images per second. Applications being investigated include imaging of extremely rapid flow, and the monitoring of the evolution of transverse magnetization during 2D RF pulses generated with EPI gradient trajectories by modifying the pulse sequence to enable a single image during the flyback period.
