Doppler Exam: Venous A venous Doppler ultrasound is a diagnostic test used to check the circulation in the large veins in the legs (or sometimes the arms). This exam shows any blockage in the veins by a blood clot or “thrombus” formation. The veins return blood to the heart. Deep veins – which are underneath the leg muscles.

Doppler ultrasound: What is it used for? A Doppler ultrasound is a noninvasive test that can be used to estimate the blood flow through your blood vessels by bouncing high-frequency sound waves (ultrasound) off circulating red blood cells. A regular ultrasound uses sound waves to produce images, but can't show blood flow.

Doppler Exam: Leg Arterial Doppler Exam: Leg Arterial. What is a Leg Segmental Arterial Doppler Ultrasound Exam? A leg arterial exam is a test that looks at the blood circulation in the arteries of your arms or legs to see if there is any blockage. The function of blood circulation is transportation – bringing food and oxygen to the body’s cells and organs.

Doppler ultrasound pulse wave Doppler ultrasound a technique in which the transducer emits ultrasound in pulses. Blood flow velocities so measured are limited to around the physiologic range (up to approximately 1.5 meters/second) but the depth from which the returning echoes originate can be accurately determined.

Carotid Ultrasound Carotid (ka-ROT-id) ultrasound, also called Doppler ultrasound or Carotid duplex ultrasound, is a painless and harmless test that uses high-frequency sound waves to create pictures of the insides of the two large arteries in your neck. These arteries, called carotid arteries, supply your brain with oxygen-rich blood.

- What It Is. A foot X-ray is a safe and painless test that uses a small amount of radiation to make an image of a person's foot. During the examination, an X-ray machine sends a beam of radiation through the foot, and an image is recorded on special X-ray film or a computer. This image shows the soft tissues and bones of the foot, which include the tarsal bones (ankle bones), metatarsal bones (front end of foot), and phalanges (toes).

Imaging and Tests for Foot Pain For diagnosing problems, such as tarsal tunnel syndrome, where there is compression of the nerve, a doctor may use electrodiagnostic tests, such as nerve conduction studies and electromyography. For nerve conduction studies, the doctor fastens electrodes to the ankle and foot, then sends small electric shocks to the nerves in the lower leg, ankle, and toes, and measures the speed of conduction of nerve fibers.

""" How long does it take to get the results from a leg venous doppler? """ Diagnosis is achieved by performing a Doppler ultrasound of the legs. The test itself takes 15-30 minutes to perform. The timing of the result depends on who interprets the findings (radiology technician, radiologist, vascular medicine physician, etc). Generally speaking the result should be available within several hours but can take up to a day.

Doppler radar noun. Doppler radar is defined as a tracking system that uses the Doppler effect to determine the change in the frequency, movement and location of sounds, objects, waves of light, storms and other weather elements. 1  An example of Doppler radar is what a weatherman uses at a local TV news station to forecast storms.

- A Doppler ultrasound test uses reflected sound waves to see how blood flows through a blood vessel. It helps doctors evaluate blood flow through major arteries and veins, such as those of the arms, legs, and neck. It can show blocked or reduced flow of blood through narrow areas in the major arteries of the neck that could cause a stroke .

- Doppler ultrasound 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. Doppler ultrasound study – a technique that evaluates blood flow through a blood vessel – is usually part of this exam. Ultrasound does not use ionizing radiation, has no known harmful effects, and provides a clear picture of soft tissues that don’t show up well on x-ray images.
