Transient arterial phase respiratory motion-related artifact

Transient arterial phase respiratory motion-related artifact refers to common self-limited dyspnea observed immediately after the administration of gadoxetate disodium during liver MRI studies. The physiopathology behind this phenomenon is poorly understood and its incidence varies among different publications in a range between 2.4 and up to 18% .

Although described with other gadolinium agents, this self-limited dyspnea is much more prevalent with gadoxetate disodium. Awareness about this potential artefact when choosing for these hepatospecific contrast agents (Primovist and Eovist) is vital, as the motion degradation of the images can be non-diagnostic.
