title: Level IIb CTV delineation based on cervical fascia anatomy in nasopharyngeal cancer.
abstract: We carefully reviewed magnetic resonance (MR) images from 100 consecutive NPC patients and analyzed the lymph node distribution status at level IIb. We proposed several modifications of the existing consensus guidelines for determining the level IIb clinical target volume (CTV) in NPC patients.
