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

The method of radionuclide venography is best determined by the localisation and type of suspected venous abnormality. The authors describe four methods using 99mTc microspheres and 99mTc-pertechnetate. Correlation of the isotope and angiographic findings in 150 patients indicated an accuracy of 90% for the isotope methods. The risks of radionuclide venography are discussed. Isotope venography is recommended as a simple, non-invasive technique.
