Radionuclide venography and the role of radionuclides in the detection of venous disease.

Until recently, the true incidence of venous thrombosis in the general population was difficult to determine. However, with the availability of noninvasive screening techniques, such data are now being gathered. The incidence of calf vein thrombosis, as measured by the fibrinogen uptake test in inpatient (medical and surgical) population, ranges from 30% to 60%.’ In carefully examined autopsy specimens, the incidence of deep vein thrombosis in the leg varied from 26% to 86%.’-’ 2
