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.
