[Isotope methods in the diagnosis of venous disease. II. Results of radionuclide venography (author's transl)].

The frequency of scintigraphic findings in the presence of thromboses, post-thrombotic changes and in normal veins, was determined in 150 patients. The results of radionuclide venography and contrast venography in these patients have been compared. Abnormalities in veins can be detected by radionuclide venography with a high degree of accuracy. Differentiation between acute and chronic thrombosis and post-thrombotic changes can only be made by invasive contrast venography.
