Arterial edge artifacts in gated, phase re-ordered phase contrast angiography of the extremities.
Cardiac gating and phase re-ordered acquisition are often employed to reduce pulsatile flow artifacts in MR angiography. When these techniques are used in conjunction with phase contrast angiography in the extremities they can produce arterial edge artifacts.
