In this article, we compare the usefulness of multiple arterial phases (APs) and a relatively short breath-hold single AP to reduce the motion artifact in gadoxetic-acid-enhanced MRI. The transient motion artifact (TMA) score and phase timing of the AP in 540 consecutive patients were retrospectively analyzed. Our results showed that the best mean TMA score for multiple APs was significantly lower than that for the conventional single AP, but a relatively short breath-hold single AP did not reduce the incidence of TMA. In addition, multiple APs can capture more satisfactory ones, which meets clinical diagnostic requirements.
