Concomitant (Maxwell) fields are problematic for TSE imaging when the readout waveforms vary along the echo train, leading to severe signal dropouts and image blurring. These effects are exaggerated when using prolonged, high-gradient amplitude readouts at lower magnetic-field strengths. The purpose of this work was to implement 2D TSE imaging using annular spiral rings with compensation of self-squared concomitant-gradient terms at the echo time and across echo spacings via gradient waveform modifications, and with compensation of the residual Maxwell- and B0-field induced phase accruals along the readout via image reconstruction. This method reduced artifacts at both 0.55T and 1.5T.
