  • Title: Radionuclide venography vs Tc-99m-RBC equilibrium angiography: a comparative paired study.
    Author: Oster ZH, Atkins HL, Trivedi M.
    Journal: Eur J Nucl Med; 1987; 13(4):174-82. PubMed ID: 3622564.
    Abstract:
    Combined direct injection venography (DIV) and equilibrium angiography (EA) were performed in 13 patients, by injecting in vitro labeled 99mTc autologous RBC, via pedal veins, and imaging the first pass and the equilibrium phase. This paired comparative study of DIV with EA shows that DIV has advantages over EA because it provides selective information on the deep venous system from the calves to the inferior vena cava. DIV provides information on the flow dynamics and the high contrast first pass images provide better definition of non filling venous segments as well as visualization of collaterals. When using 99mTc-MAA, lung perfusion can also be imaged. DIV is recommended as the procedure of choice for the diagnosis of DVT and EA should be employed only when pedal vein injection is not possible.
