Ultrasonography of deep vein thrombosis
Ultrasonography in suspected deep vein thrombosis focuses primarily on the femoral vein and the popliteal vein, because thrombi in these veins are associated with the greatest risk of harmful pulmonary embolism.

Medical uses[edit]
The risk of deep vein thrombosis can be estimated by Wells score.
Lower limbs venous ultrasonography is also indicated in cases of suspected pulmonary embolism where a CT pulmonary angiogram is negative but a high clinical suspicion of pulmonary embolism remains.[1] It may identify a deep vein thrombosis in up to 50% of people with pulmonary embolism.[1]
Knee or hip replacement are, by themselves, not indications to perform the procedure.[2]
Serial follow-up the ultrasound exam is not necessary after an initially complete, normal study in individuals with DVT symptoms who have suspected pulmonary embolism and nondiagnostic ventilation/perfusion scans .[3]
