Procedure- Sonogram of the Arteries in the Neck
A sonogram is a test that sends high pitched sound waves through your skin, and the echoes form a picture on a TV monitor. This test measures blood flow through your arteries. It is useful for locating blockages. This test is non-invasive (there is no penetration of the skin by needles, etc.).
Before The Procedure
- There are no special preparations for this test.
During The Procedure
- A water based gel is used to keep contact with the skin. The sound waves then produce a visual and sound image on a monitor.
- While the technician does the test she may be making a video tape for your physician to watch. The technician will be talking into the machine telling your physician what the test shows about your vascular system. You may hear your heart beat and/or a whooshing sound as your blood flows.
