Abstract

Objectives: To compare diagnostic accuracy of gadoxetic acid-enhanced magnetic resonance imaging (MRI) (original set) and original MRI combined with the arterial phase of low-tube-voltage computed tomography (CT) (hybrid set). Methods: In hybrid set, we substituted the CT arterial phase for MRI arterial phase. Three observers independently interpreted. The accuracy of each image set was evaluated using the alternative-free response receiver operating characteristic method. Results: The mean Az values for original set (0.96±0.01) was higher than that for hybrid set (0.94±0.01), but the difference was not significant (. P=. .10). Conclusions: In cases with degradation of magnetic resonance arterial phase, reuse of CT arterial phase might be helpful instead of repeating MRI.
