Motion artifacts in 2D TOF MRA

Motion-induced artifacts in 2D TOF MRA, 1.5 T

Fig 1. Sagittal MIP reconstruction of the common carotid artery bifurcation from a 2D TOF MRA acquisition data set. Signal voids and inaccurate (staircase-like) vessel wall alignment (arrow), due to patient motion and/or swallowing. This kind of artifact is typical for 2D TOF acquisition, due to the sequential acquisition of each slice within the volume of interest.
