Vascular Testing - Doppler
Non-Invasive Vascular Testing
Our Vascular Department has been accredited by The Intersocietal Commission for the Accreditation of Vascular Laboratories. Vascular studies are non-invasive, painless tests that are performed using Doppler ultrasound. Doppler uses high frequency sound waves to create images.
We offer the following studies in our office:
- Carotid Doppler: Evaluates blood flow through the carotid arteries to the brain. Plaque build-up can cause blockages that could lead to stroke.
- Arterial Doppler: Evaluates exercise-induced pain in extremities that could be caused by a blockage in the arteries that supply blood. Arterial Doppler is also performed after surgical intervention to determine patency of grafts.
- Venous Doppler: Evaluates redness, pain and swelling in the extremities that could be caused by a blood clot in a vein.
- Abdominal/Renal Doppler: Determines the presence of an abdominal aortic aneurysm or blockage of the arteries that supply blood to the kidneys.
The above studies are performed by a Registered Vascular Technologist and take approximately 45-60 minutes.
How to Prepare
Patients undergoing abdominal imaging should have nothing to eat or drink from midnight the night before the test. Gas-X is required to be taken the night before the test and again prior to the test (available over the counter).
Patients undergoing renal imaging are required to take Gas-X at night and again prior to the test. Patients should have nothing to eat from midnight before the day of the test. The technologist will instruct you to drink 8 oz. of water just prior to starting the test.
