Answer

Venography and duplex scanning (ie, ultrasonography combined with Doppler velocity waveforms) are used to assist in the diagnosis of subclavian vein compression (thrombosis). These tests can be performed dynamically with positions that recreate the tension placed on the thoracic outlet during certain motions such as abduction and external rotation.
