Introduction: Dynamic B0 off-resonance, caused by respiration or scanner drift, leads to dynamic image artifacts in fast imaging sequences, such as pixel shifts in phase-encode (PE) direction for blipped EPI or blurring for spiral EPI. Common means to detect and correct these B0-induced artifacts are navigator signals [1] and methods such as DORK [2], which so far have been demonstrated and applied widely to magnitude image time series used for fMRI, diffusion or perfusion. In contrast, studies… CONTINUE READING
