Test Details

How does vascular ultrasound work?

Vascular ultrasound uses high-frequency sound waves to create detailed images. These sound waves pass through your soft tissues and blood vessels. Sound waves create echoes as they pass through tissue and computers turn these echoes into images or videos.

How do I prepare for a vascular ultrasound?

There’s nothing special you need to do to prepare for a vascular ultrasound. Plan to arrive at the facility about 15 minutes before your vascular ultrasound appointment.

You should wear comfortable and loose-fitting clothing and leave any jewelry or valuables at home. Healthcare providers may ask you to change into a hospital gown.

What happens during a vascular ultrasound?

You lie on an examination table. The technologist applies a lubricating gel to your skin in the areas where they will examine your arteries and veins.

The technologist places a special probe called a transducer against your skin. You might feel a little pressure as they move the probe over the area. You may hear your blood flowing as it makes a pulsing or whooshing sound.

What should I expect after the vascular ultrasound?

When the exam is over, the technologist wipes the lubricating gel away. You can return to work or other activities immediately after your exam.

Does vascular ultrasound have any risks or side effects?

Vascular ultrasound is safe. You won’t have any side effects from the exam.

Results and Follow-Up

What results do healthcare providers get from vascular ultrasound?

Vascular ultrasound gives your healthcare provider information about how quickly (or slowly)blood flows through your body. This tells your provider if something is blocking a blood vessel (like a blood clot or plaque) or if blood vessels have become narrow.

How long does it take to get results from a vascular ultrasound?

A doctor who specializes in reading and interpreting radiographic images (radiologist) evaluates the images. When the radiologist has completed their review, they send the results to the doctor who ordered your vascular ultrasound.

When should I call my healthcare provider after a vascular ultrasound exam?

You shouldn’t expect any side effects from a vascular ultrasound exam. Let your healthcare provider know if you develop any new or worsening symptoms such as pain or redness in the examined area.
