Key result
Swallowing, breathing, and arterial pulsation induce significant carotid artery motion during MRI, reaching ~4.7 mm.
Why the study?
What are the sources and amplitudes of motion artifacts in carotid artery MRI?
Observational (n=14)
What are the sources and amplitudes of motion artifacts in carotid artery MRI?
Arterial pulsation, breathing, and swallowing induce significant motion in the carotid artery wall, highlighting the need to account for these artifacts to improve MRI quality.

Motion compensation needed in carotid MRI protocols; Level 4 data leaves optimal techniques open for validation.
Boussel et al. (2006) conducted an observational in Atherosclerotic disease (n=14). Arterial pulsation, breathing, and swallowing was evaluated on Isocenter carotid artery motion amplitude. Arterial pulsation (mean amplitude 0.6 mm), breathing (1.56 mm), and swallowing (4.7 mm) induced significant motion in the carotid artery wall during MRI.
