The clinical study of radionuclide venography in the diagnosis of lower extremity deep venous thrombosis

Objective To explore the value of radionuclide venography(RNV) in the diagnosis of lower extremity deep vein thrombosis(DVT). Methods One hundred and seventy-seven patients suffering from suspected lower extremity DVT the ⁹⁹Tc^m-macroaggregateed albumin(⁹⁹Tc^m-MAA) RNV examination by SPECT.Results The sensitivity,specificity and accuracy of RNV in the diagnosis of DVT were 92.1%(1 29/140),83.7%(31/37),90.3%(160/177).DVT had a typical imaging feature of the RNV.Conclusio RNV is safe,non-invasive and simple.The sensitivity,specificity and accuracy of RNV are higher.And it can reflect the functional status of the veins of the patients with DVT more accurately.RNV is a reliable method in the diagnosis of lower extremity deep venous thrombosis.
