Vascular Ultrasound

In This Page:


Vascular ultrasound is a diagnostic imaging technique that uses high-frequency sound waves to produce images of the body’s veins and arteries. Jefferson Radiology’s vascular lab is accredited by the Intersocietal Commission for the Accreditation of Vascular Laboratories (ICAVL). It is staffed by Registered Vascular Technologists (RVT's) and Board Certified Interventional Radiologists with specialized training in performing and analyzing vascular disease.

Need to Know

Nice to Know
  • You may be asked to change into a gown prior to the procedure
  • You may be instructed to fast prior to the exam for abdominal vascular exams.

The exam is painless, non-invasive and radiation-free. There are no known side effects to ultrasound.


Why is This Exam Done?

Vascular ultrasounds are commonly used to monitor the flow of blood to tissue and organs within the body. This procedure can also be used to determine the severity of a person’s varicose veins or to find enlarged arteries.  Blood clots and deep vein thrombosis may also be detected through a vascular ultrasound. This procedure will detect tumors, narrowing of blood vessels, and any blockages to blood flow.

What Will Happen During the Exam?

The sonographer will request that you lay quietly during the test to help ensure that the images are clear.  Warm, water-based gel will be applied to the ultrasound transducer or directly on the skin.  The sonographer will then move the transducer around on the area to obtain clear images of the underlying structures and vessels for the physician to interpret.

The procedure typically lasts for 30 to 60 minutes, but the duration varies depending on the structure being examined.

How Does it Work?

Ultrasound uses high-frequency sound waves to produce images of the body’s tissues, structures, and blood flow.  A transducer/probe and ultrasound gel work in combination to absorb the reflected sound waves to produce images on the monitor.
