title: Fast MRI by creating multiple spin echoes in a CPMG sequence.
abstract: A fast multislice imaging technique has been developed. RASTER (Rapid Acquisition with STimulated Echo Refocusing) is based on RARE (Rapid Acquisition with Relaxation Enhancement), and creates multiple spin echoes/each 180 degrees pulse utilizing stimulated echoes, and phase encode each differently. The sequence can be much faster than RARE while keeping the same spin echo image contrast. The main limitation of the technique is reduced signal-to-noise ratio.
