Answer

Sialography can be used to evaluate sialolithiasis or other obstructive entities, as well as inflammatory and neoplastic disease. In this technique, a water-soluble medium such as meglumine diatrizoate is injected into the Wharton duct and lateral, oblique, and anteroposterior plain radiographs are obtained in order to assess the ductal arborization. Contraindications for this test are iodine allergy and acute sialadenitis.

Any filling defects (eg, calculi), retained secretions (eg, chronic sialadenitis), stricture formation (eg, inflammation), extravasation (eg, Sjögren disease), or irregularly contoured borders (eg, neoplasm) are noted.
