[Quantitative functional scintigraphy of the salivary glands. I. Determination of global and regional gland function].
A method for quantifying the function of the salivary glands using the dynamic scintigraphy with 99mTc is presented. After a special back-ground subtraction, the net-time-activity curves of the glands are characterized by 4 quantitative parameters, describing the ability of the glands to accumulate and to excrete the tracer. As a basis for clinical application, normal values are determined and their reproducibility is discussed. To demonstrate also regional functional differences within a single gland, phase-and gradient images are suggested.
