Radionuclide venography: rapid dynamic visualization of the venous system

Although contrast phlebography remains the diagnostic standard for detection of thrombophlebitis, patient discomfort and other factors limit routine use of venography for screening or follow-up purposes. Furthermore, the iliofemoral veins and vena cava are not routinely visualized with this technique. This investigation assessed a relatively simple radionuclide method to visualize the major veins of the lower extremities and abdomen. (U.S.)
