Addressing concomitant gradient phase errors in time‐interleaved chemical shift‐encoded MRI fat fraction and R2 mapping with a pass‐specific phase fitting method

Purpose Concomitant gradients induce phase errors that increase quadratically with distance from isocenter. This work proposes a complex‐based fitting method that addresses concomitant gradient phase errors in chemical shift encoded (CSE) MRI estimation of proton density fat fraction (PDFF) and R2*...
