Key result
The 131I-M.A.A. radioisotope test demonstrated 86% agreement with phlebography in detecting deep venous thrombosis and 90% agreement in confirming its absence.

Does a radioisotope test using labelled M.A.A. accurately detect deep venous thrombosis in the legs compared to phlebography in patients with suspected DVT?
A bedside radioisotope test using labelled M.A.A. shows high diagnostic agreement with phlebography for detecting deep venous thrombosis in the legs.
Duffy et al. (1973) conducted an observational in Deep venous thrombosis (n=31). 131I-labelled macroaggregates of albumin (M.A.A.) scintiscanning vs. Phlebography was evaluated on Agreement with phlebography for the presence of thrombosis. The 131I-M.A.A. radioisotope test demonstrated 86% agreement with phlebography in detecting deep venous thrombosis and 90% agreement in confirming its absence.
