Learning objectives: Describe the symptoms and imaging findings associated with transient severe motion artefact (TSM) Highlight the incidence, risk factors and clinical significance of TSM.
Background: Given its excellent soft tissue differentiation, magnetic resonance imaging (MRI) is firmly established as the modality of choice in liver imaging. Gadoxetate disodium (Primovist/Eovist®) and gadobenate dimeglumine (MultiHance®) are hepatobiliary agents developed over the last two decades. In [...]
Findings and procedure details: Transient Severe Motion Artefact TSM is a self-terminating occurrence that results in motion artefact and distortion of arterial phase imaging, improving or resolving on later dynamic sequences. Although it is hypothesised that mismatching of the k-space acquisition with the bolus due to rapid gadox[...]
Conclusion: Transient severe motion artefact is a significant clinical problem following gadoxetate disodium-enhanced hepatic MRI that renders over 10% of arterial phase sequences non-diagnostic. Although a self terminating phenomenon, such patients have a higher rate of artefact recurrence on subsequent exami[...]
