Duplex Scanning of the Veins of the Upper Limbs is a non-invasive imaging study that combines B-mode sonography and Doppler assessment to evaluate the structural and hemodynamic condition of the venous system of the upper limbs.

The examination provides information on the direction and velocity of blood flow in both deep and superficial veins and also assesses the functional state of the venous system.

Duplex Scanning of the Veins of the Upper Limbs is widely used in clinical practice, as it delivers data with high diagnostic accuracy, is safe and repeatable, and does not involve exposure to ionizing radiation, which further enhances its value in the evaluation and monitoring of the venous system.
