title: [Functional imaging of characteristic kinetic parameters of kidney and thyroid (author's transl)].
abstract: A procedure has been developed by which the reaction of an organ to a very short delta-function activity pulse of an organ-specific tracer introduced into the blood can be determined for the kidney and the thyroid. The data for the procedure are available from sequence scintigrams and the change with time of the activity of the tracer in the blood. The nature and duration of this reponse function makes it possible to calculate organ-specific parameters such as uptake rates, clearance rates or transit times. They may be calculated for the total field of the gamma camera and delineated as grey or colour gradations to yield the respective parametric functional images. The apparatus necessary for the procedure is described and its possible clinical application in comparison to conventional scintigraphic procedure is discussed.
