Imaging of the salivary glands.

The most common conditions affecting the salivary glands are calculi, inflammation and tumours. Plain radiography may be useful, especially in showing calculi. Sialography is the examination of choice for inflammatory diseases, whereas ultrasonography, computed tomography and magnetic resonance imaging are particularly useful in evaluating masses in the salivary glands. Radionuclide studies are sometimes helpful in evaluating inflammatory or tumoral diseases. Each technique has its place, and the methods are often complementary. In this review article the authors present the techniques that they use in evaluating diseases of the salivary glands.
