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. You will be taken to the Vascular Lab in a wheelchair or by stretcher. During The Procedure If you go by wheelchair, you will then lie on a bed in an exam room for the test. There will be a short wait while the Vascular lab technician reviews your chart. 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, he/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 heartbeat and/or a whooshing sound as your blood flows. After The Procedure After a brief wait, you will be taken back to your room by wheelchair or stretcher. Your physician will explain the results of the tests after he/she views the video.
