[Quantitative gated radionuclide cine cardiography. I Technical basis and methods (author's transl)].

Scintigraphic evaluation of the heart function is performed by means of sequential camera scintigraphy following i.v. injection of a 99mTc albumin bolus. The first tracer passage is registered during 30 seconds. About 10 minutes later--after equilibration of the tracer in the blood pool--volume curves of the left ventricle are recorded from a series of about 500 heart cycles. The principles of a computer program which has been developed for this method are described and discussed in detail.
