The purpose of our present study was to evaluate the incidence of TSM at gadoxetate disodium-enhanced MRI using different contrast application protocols, i.e. by variation of contrast injection rate, dose and supplemental nasal oxygen application. In addition to quantitative SNR measurements, motion artifacts and arterial phase image quality were compared. The overall incidence of TSM in our study population was 11.5%, and neither variation of contrast application parameter was able to significantly reduce the occurrence of these artifacts.
