RASER(Rapid Acquisition by Sequential Excitation and Refocusing) sequence acquires all the echoes with same TE by using two refocusing pulses [1], whereas other spatiotemporal-encoding(SPEN) techniques using a single-refocusing pulse offers a shorter effective TE than RASER but with varying TE, thereby causing signal variation in the SPEN dimension [2]. Here, we propose an effective way of overcoming this problem of TE variation in single-refocusing SPEN imaging.
