title: Assessment of salivary gland function in Sjögren's syndrome: the role of salivary gland scintigraphy.
abstract: Salivary gland scintigraphy (SGS) is a non invasive method of salivary gland function assessment. This technique is easy to perform, reproducible and well tolerated by patients. Additionally, an abnormal salivary gland scintigraphy result is accepted by the American-European consensus group as a criterion for the diagnosis of Sjögren's syndrome. Scintigraphic evaluation of salivary gland function also plays an important role in therapeutic decision and patient follow-up. Schall's categorical classification is usually considered the standard method for salivary scintigraphy interpretation, though subjective and with limited capacity to discriminate borderline results. In order to improve the diagnostic accuracy of SGS, there has been an increasing interest in the quantification of glandular function. However, the debate on the most reliable and suitable parameters for the diagnosis of SS persists.
