title: Using dynamic maneuvers in the computed tomography/magnetic resonance assessment of lesions of the head and neck.
abstract: Despite advances in technology, the radiologic assessment of certain head and neck lesions may still pose difficulties because of the complex anatomy of this region, the small and mobile structures that this region harbors, and the apposition of mucosal surfaces in the neutral position. Certain maneuvers have been described in the literature to overcome these difficulties. We review the use of the Valsalva and the modified Valsalva maneuver, the puffed-cheek technique, phonation, and inspiration, with possible applications in head and neck imaging.
