Vascular Ultrasound uses the same technology as Echo where sound waves are used to visualize the larger arteries such as the carotids in the neck, the aorta in the abdomen, the arteries leading to the kidneys, and the arteries leading to both legs. With this testing we can look for plaque or narrowing in these arteries and estimate the amount of blockage. This is also a non-invasive test meaning that no needles are involved. These tests are similar to ultrasounds performed on pregnant women to look at babies in utero; but in this case are directed at specific arteries and/or the heart. This is a very safe and painless test.
