Dynamic computed tomography of the head and neck: differential diagnostic value.

Abstract
A retrospective review of the dynamic CT [computed tomography] studies performed on [human] head and neck lesions, excluding the brain, was carried out. Five basic types of density vs. time curves were obtained. Dynamic CT scanning is valuable in the differential diagnosis, management and followup of such cases; its usefulness as an imaging modality in diagnosis and followup of hemangiomas is stressed.
