Off-resonance effects can lead to geometric distortion of slice profiles at higher fields, which often goes unnoticed. We explored the problem at 3T using a system equipped with an 8-channel parallel transmission body coil. It is demonstrated that a slab selective excitation which is noticeably bent can be straightened by use of tailored pulses without changing the gradient trajectory, opening up the possibility that such a correction can be made an add-on to standard sequences.
