Techniques have recently been proposed to correct the susceptibility-induced distortions in MR images near metallic implants. The slice-encoding for metal artifact correction (SEMAC) method applies additional slice encoding, which almost completely corrects in-plane and through-plane distortions at a cost of additional scan time. Here we show that with a linear reconstruction SEMAC imaging can be performed with spin echo trains and both parallel imaging and partial Fourier imaging to provide flexible contrast in reasonable scan times.
