The aim of this study was to determine whether the recently developed non-contrast-enhanced Inhance 3D velocity magnetic resonance angiography (Inhance 3D MRA) technique is capable of evaluating the course of facial artery (branch artery) in preoperative evaluation of vacularized submental lymph node flap. The result shows that Inhance 3D MRA is a promising method for assessing facial artery course without concerning the contrast media (CM) travel time and the venous contamination.
