Is there a dosimetric advantage of volumetric modulated arc therapy over intensity modulated radiotherapy in head and neck cancer?

VMAT shows dosimetric superiority to IMRT in some cases, however an adequate coverage of the target volumes and a suitable OAR sparing can be achieved with both techniques. Though IMRT is still the standard in HNC radiotherapy, VMAT can be safely implemented, offering at least similar target coverage and organ sparing, with significantly reduced MU.
