title: Pictorial essay: early- and late-term effects of radiotherapy in head and neck imaging.
abstract: The purpose of this article is to illustrate the cross-sectional imaging appearance of postradiation changes and complications of radiotherapy in the head and neck. Radiotherapy is an important treatment modality for head and neck cancer, and is often used in conjunction with chemotherapy. Recognition of the varied effects of radiotherapy to the head and neck region is essential to correctly interpret posttreatment imaging and may help prevent further complication.
