In This Page:

Venous ultrasound is a diagnostic imaging technique that uses high-frequency sound waves to produce images of the body’s veins.

Need to Know

Nice to Know
  • You may be asked to change into a gown prior to the procedure
  • Ultrasound is a painless, non-invasive, radiation-free diagnostic test that uses high-frequency sound waves to create images of body tissues
  • You may be instructed to fast prior to the exam if the veins being examined are in the abdomen
  • The exam is painless, non-invasive, and there are no known side effects
  • Ultrasound uses sound waves higher than human hearing can detect


Why is This Exam Done?

Venous ultrasounds are commonly used to discover potentially dangerous blood clots in the legs, known as Deep Vein Thrombosis. If discovered early enough it is possible to treat these clots before they move to the lungs. Venous ultrasounds can be used to map an individual’s veins, in order to aid in the transferring of pieces of veins for use in bypass surgery. Venous ultrasounds are used in the treatment of varicose veins.

What Will Happen During the Exam?

Our experienced and caring sonographers who will be performing your exam are specifically accredited in Ultrasound, and have been trained on our state of the art equipment.

The ultrasound sonographer will request that you lay quietly during the test to help ensure that the images are clear. He or she will then apply a special gel directly on the skin above the area to be examined to increase sound wave conduction and reception. The sonographer will then press the transducer against your skin and may move the transducer back and forth to get clear images of the underlying blood vessels and structures.

The procedure typically lasts for 30-45 minutes, but the duration varies depending on the structure being examined.
