What is an arterial duplex ultrasound?
Ultrasound is a procedure that uses sound waves to “see” inside your body. An arterial duplex ultrasound uses sound waves to create a color map of the arteries in your legs to identify: Narrowing of your vessels that may be causing leg pain when walking.
What is the difference between duplex ultrasound and Doppler ultrasound?
A duplex ultrasound combines: Traditional ultrasound: This uses sound waves that bounce off blood vessels to create pictures. Doppler ultrasound: This records sound waves reflecting off moving objects, such as blood, to measure their speed and other aspects of how they flow.
What is the purpose of a duplex ultrasound?
Duplex ultrasound is used to assess the arteries of the leg for the presence of atherosclerosis (disease and narrowing of the arteries). Patients with significant narrowing or occlusion of the arteries in the abdominal aorta, iliac arteries and arteries of the leg often experience claudication.
What does an arterial duplex show?
An Arterial Duplex is an ultrasound test that uses high frequency sound waves (ultrasound) and a series of blood pressure cuffs to show and measure blood flow in the arteries of the arms and legs.
How long does a duplex scan take?
The technologist will apply a warm gel to your legs and a transducer or a small microphone will be used to examine your arteries. You will hear the sound of moving blood during the exam. Do not be alarmed; it is harmless. Your exam will take approximately 15 to 30 minutes.
What is an aortic duplex?
An Abdominal Aortic-Iliac Duplex is an ultrasound test that uses high frequency sound waves (ultrasound) to evaluate the aorta, the main artery in the abdomen, and other arteries that deliver blood to the major organs in the body.
What is the difference between arterial duplex and Doppler?
The arterial duplex exam has two parts which are done simultaneously. One part, the 2-D echo, produces images of the arteries in the extremity. The second part of the test is known as the Doppler component. This produces sounds that you will hear and helps the physician evaluate the blood flow through the arteries.
How is the duplex ultrasound performed?
When performing duplex ultrasound, your physician uses the two forms of ultrasound together: Conventional ultrasound uses painless sound waves. A computer converts the sound waves into two-dimensional, black and white moving pictures. Duplex Doppler ultrasound measures how sound waves reflect off of moving objects.
Can you eat before a leg ultrasound?
It is commonly used to search for blood clots, especially in the veins of the leg – a condition often referred to as deep vein thrombosis. Ultrasound does not use ionizing radiation and has no known harmful effects. On occasion, you may be asked not to eat or drink anything but water for six to eight hours beforehand.
Which leg is your main artery in?
Femoral artery
The femoral artery is a large artery in the thigh and the main arterial supply to the thigh and leg. The femoral artery gives off the deep femoral artery or profunda femoris artery and descends along the anteromedial part of the thigh in the femoral triangle.
What is a duplex arterial?
Arterial Duplex. An arterial duplex utilizes sound waves to obtain images of the arteries in the legs or arms. The harmless sound waves leave a transducer that is placed at various points on the legs or arms and the sound waves are bounced back to the transducer and converted to images.
What is arterial duplex test?
An Arterial Duplex is an ultrasound test that uses high frequency sound waves (ultrasound) and a series of blood pressure cuffs to show and measure blood flow in the arteries of the arms and legs.
What is an arterial duplex study?
Arterial Duplex Study. An Arterial Duplex Study is also known as LEAI (lower extremity arterial imaging) or UEAI (upper extremity arterial imaging). This test will check the arterial circulation in the arms or legs.
What is carotid duplex ultrasound?
A carotid duplex is a carotid ultrasonography carried out by duplex ultrasonography. A duplex carotid ultrasound may include a Doppler ultrasound, a special test able to reveal the movement of blood cells through the carotid arteries.
