✦ Synopsis

We have already considered both phase and amplitude discontinuities as soiirces of ringing i n alternate k-space sampling. Through the over sampling of the 96"' line of k-space, we were able to more accurately correct for discontinuity at this point. That is not to say that we applied this Same correction to the 32nd line. ~~~l we corrected for discontinuity at this point by noting the amplitude of adjacent lines of k-space. We stated: "The

## Abstract In this work, preliminary results are described for a modification of the MBEST sampling scheme such that image resolution can be increased while preserving image contrast. In this new approach, a single spin‐echo is used in sampling __k__‐space. The basic idea relies on acquiring a con
