STEAM diffusion offers longer diffusion times, reduced gradient demands and other advantages for diffusion imaging but has suffered from long acquisition times. We propose a non-selective preparation of a conventional gradient echo echoplanar sequence that enables the rapid acquisition of many slices. Initial application to the brain readily enabled up to 32 slice acquisition within a single TR.
