Contemporary imaging of parotid gland and parapharyngeal space.

: Clinically, the parotid gland and associated parapharyngeal space can be assessed better using selective diagnostic imaging as an adjunct. It increases the effectiveness of management and the pretreatment staging of disease. This paper reviews the available specific imaging modalities (conventional x-ray films, contrast sialography, computed tomography, magnetic resonance imaging, ultrasonography, angiography and radionuclide scanning), their current indications and potential limitations.
