carotid duplex scan:

This information is provided exclusively for Queen's Heart patients. Please review this infomation carefully before arriving for your test.

A Carotid Duplex Scan, also know as a Carotid Ultrasound, uses sound waves to produce images of how well and how much blood is flowing through your carotid and vertebral arteries which supply blood to your head and brain. The images are much like a movie and allow your doctor to see and hear the blood flow and determine if there are any blockages or narrowings which may reduce blood flow to your head and brain.

Approximately 45 minutes to 1 hour.

There is no special preparation for the test. However, if you smoke tobacco please do not smoke for 4 hours before the test as this will cause abnormal results.
