2D spatial excitation using Tx-SENSE is frequently combined with a conventional, slice selective refocusing pulse to restrict the signal in the third dimension. Severe B1+ inhomogeneities of the refocusing pulse at 7T compromise the resulting image quality even if B1 shimming is applied. We present phantom experiments with adapted Tx-SENSE pulses to address this problem.
