[Quantitative functional scintigraphy of the salivary glands--clinical possibilities and current indications]

A special background subtraction in dynamic scintigraphy of the salivary glands enables the production of net-time-activity-curves and the calculation of quantitative parameters of each gland. Regional functional differences within a single gland are shown by phase and gradient images. The physiological kinetics of the tracer and its modifications in different diseases of the glands (acute and chronic inflammation, tumours, Sjögrens-Syndrome) are analyzed in 367 patients.
