While MR imaging of the carotid bifurcation has become a valuable tool in the detection and characterization of vascular disease, pulsatile arterial wall motion resulting from the cardiac cycle can result in blurring artefacts that diminish resolution and can cause the appearance of a thickened vessel wall. This study investigates the use of cardiac gating in high-resolution MRI to compensate for arterial wall motion in a healthy volunteer population.
