You might be asked not to consume any food or fluids except water for six to eight hours before the procedure if you have an abdominal vein examination.ĭuring the ultrasound, a transducer sends sound waves and records the echoing waves during the exam.

Venous ultrasound imagingĭuring ultrasounds, a tiny probe called a transducer and gel are mounted directly on the skin. They are also known as thrombosis of the deep vein, or DVT. Searching for blood clots, especially in the leg’s veins, is the most common reason for a venous ultrasound test. It is widely used, especially in the veins of the leg, to check for blood clots. In order to create images of the veins in the body, venous ultrasound uses sound waves.
