Diffusion imaging has become a crucial component of clinical and research protocols; robust and accurate diffusion encoding schemes are required to produce consistent and factual results. It was recently shown that the dual spin echo encoding scheme is prone to erroneous measurements due to concomitant fields, while the Stejskal-Tanner single spin echo encoding is susceptible to eddy currents. We present and validate an alternative encoding scheme, called bipolar single spin echo, which alleviates many of the problems encountered with current diffusion preparations.
