Vascular Ultrasound

Vascular Ultrasound

Doppler ultrasound, also called colour Doppler ultrasonography, is a special ultrasound technique that allows the physician to see and evaluate blood flow through arteries and veins in the abdomen, arms, legs, neck and/or brain (in infants and children) or within various body organs such as the liver or kidneys.

What to expect at your Vascular Ultrasound appointment.

No Preparation Is Required.


An ultrasound may require you to remove articles of clothing and you may be asked to put on a paper gown. Some jewelry articles may interfere with the test and may have to be removed. Wear loose clothing for most ultrasound types.imaging.

Before Your Test

You will be asked into the room after changing into a gown or removing clothing from the area being examined. You may be asked to take up a certain position and stay in that position for the most of the test.

During Your Test 

A technician would place a lubricating gel onto the area being examined using a device called a transducer to make contact with your skin.

After Your Test

You can remove the ultrasound gel with relative ease and no traces. You may go about your daily activities immediately after the test, unless otherwise advised by our staff. The reports will be produced by the reading physician, and shared with your referring doctor. You may discuss these results with you doctor at a follow up appointment.

Carotid ultrasound are a combination of ultrasounds and Doppler technologies to test and allow blood flow through the carotid arteries which are in the neck and carry blood to the brain. The test measures narrowing of the carotid arteries, which may lead to a stroke. It may be repeated to measure carotid stenosis progression. Combined CD and TCD testing measures blood flowing to and within the brain.
The venous duplex exam is an upper and lower extremity large vein ultrasound scan, detects deep vein thrombosis (DVT), which is potentially life-threatening, and venous incompetence or insufficiency, a condition that develops after vein walls become weakened and heart valves are damaged. Veins fill with blood, especially as you stand.
The arterial duplex exam is an upper and lower extremity ultrasound exam which helps to detect stenosis or arterial blockage. This procedure involves high frequency sound waves to detect blockages and abnormal blood flow, allowing physicians to plan medical and surgical treatments.
Arterial physiologic doppler exam combines Doppler technology and blood pressure measurements to test vascular blood flow in each extremity. A device emits high-frequency sound waves. Multiple readings are taken to develop a picture of the areas blood flow.
The abdominal and aortic duplex exam uses Doppler technology to measure the aorta’s diameter and assess blood flow to detect and monitor potentially life-threatening aortic aneurysms. This exam also is performed after aortic endograft repair, as well as to study the renal and mesenteric arteries. Which supplies blood to the large and small intestines.
