Neck radiography for soft tissue detail help define upper airway anatomy and adenoid size and exclude the possibility of rare nasal pharyngeal neoplasms.

Assessment of tonsillar size usually does not require any type of imaging; however, lateral neck radiographs can be used to determine adenoid size. Although MRI can provide very detailed images of soft tissues and bony structures underlying the nasopharynx, such images are not usually required, except in cases of suspected aberrant anatomy.
