Ultrasound in sialadenitis.

The salivary glands are located superficially and are therefore easily accessible to ultrasound (US) examination, particularly if a high-frequency probe designed for small parts is used. Hence, US examination of these organs is widely applied particularly in non-neoplastic pathologies. In this way, it is possible to obtain adequate images without the use of ionizing radiation or complex instrumentation such as magnetic resonance imaging. However, US examination requires an expert clinical knowledge and familiarity with the normal and pathological US anatomy of the area. Limitations and pitfalls linked to US examination of this area should also be kept in mind.
