- 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 cr arterial phase might be helpful instead of repeating MRI. (C) 2015 Elsevier Inc. All rights reserved.
