Why the study?
Does 99mTc-tripolyphosphate scintigraphy accurately detect leg thrombosis compared to phlebography in patients with suspected thrombosis?

Does 99mTc-tripolyphosphate scintigraphy accurately detect leg thrombosis compared to phlebography in patients with suspected thrombosis?
99mTc-tripolyphosphate scintigraphy shows high sensitivity but moderate specificity for detecting leg thrombosis compared to phlebography.
Thirtyeight patients with suspected thrombosis in the legs were investigated scintigraphically using 99mTc-tripolyphosphate. The ratio between the activity in the leg with suspected thrombosis and the other leg was calculated. The results were compared with those obtained with phlebography. A pathologically high activity ratio was found in all but one of the 18 patients in whom phlebography showed a thrombus. The ratio was normal in 13 of the 20 patients with normal phlebographic findings. The possible use of the method described as a postoperative screening test is discussed.

Linden et al. (1976) conducted a cross-sectional in Suspected thrombosis in the legs (n=38). 99mTc-tripolyphosphate scintigraphy vs. Phlebography was evaluated on Detection of thrombus (pathologically high activity ratio).
