Self-limited shortness of breath (transient dyspnea) after the injection of gadoxetic acid is a newly recognized adverse effect. This phenomenon is clinically relevant because breath-hold failure can leads to image degradation in dynamic contrast-enhanced liver MRI, particularly in the arterial phase. However, it is not clear whether the image degradation is only associated with transient dyspnea. In this study we prospectively evaluated the association between subjective transient dyspnea, oxygen saturation, breath-hold fidelity and image degradation.
