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.
