In order to improve resolution without increasing geometric distortions, there is an ongoing interest in multi-shot DWI in the prostate due to the high clinical significance of prostate DWI for tumor staging and therapy monitoring. However, intershot phase variations require phase error estimation and correction to reconstruct the multi-shot DWI data. Since free-breathing scans are normally used in prostate DWI, respiratory motion can be a significant source of phase errors in the prostate. The present work aims to characterize and investigate the link between respiratory motion and phase errors in the prostate.
