Doppler ultrasound exam of an arm or leg Doppler ultrasound exam of an arm or leg. This test uses ultrasound to look at the blood flow in the large arteries and veins in the arms and legs. The test is done in the ultrasound or radiology department or in a peripheral vascular lab. During the exam: A water-soluble gel is placed on a handheld device called a transducer. This device directs high-frequency sound waves to the artery or veins being tested.

Carotid ultrasonography Color flow ultrasonography (Doppler) of a carotid artery - scanner and screen Carotid ultrasonography is an ultrasound-based diagnostic imaging technique to reveal structural details of the carotid arteries, so as to look for blood clots, atherosclerotic plaque buildup, and other blood flow problems. 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. See also.

ULTRASOUND OF THE LEG ARTERIES - Normal ROLE OF ULTRASOUND. 1  To date, there have been many criteria proposed for grading the degree of arterial narrowing from the duplex scan. Criteria which have been devised for the carotid duplex scan cannot be used for the peripheral arteries. 2  Our clinics follow criteria proposed by Cossman et al 1989.

Arterial blood gas test An ABG test usually involves a radial artery puncture using a thin needle and syringe and drawing a small volume of blood,[1] but sometimes the femoral artery in the groin or another site is used. The blood can also be drawn from an arterial catheter.

- To assess blood flow in the limbs, pulse volume recordings (PVRs) may be performed. Blood pressure cuffs are inflated on the limb and blood pressure in the limb is measured using the Doppler transducer. To assess the carotid arteries in the neck, a carotid duplex scan may be performed.

Endovascular Interventions on the Iliac Artery Ipsilateral percutaneous common femoral artery access (retrograde approach) is obtained in majority of cases. In iliac lesions or aneurysms in distal external iliac artery, an antegrade approach is chosen. This involves coming from the contralateral common femoral artery using a crossover technique.

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.

Transcranial Doppler Two methods of recording may be used for this procedure. The first uses B-mode imaging, which displays a 2-dimensional image of the skull, brain, and blood vessels as seen by the ultrasound probe. Once the desired blood vessel is found, blood flow velocities may be measured with a pulsed Doppler effect probe, which graphs velocities over time.

- An arterial blood gas (ABG) is a blood test that is performed using blood from an artery.It involves puncturing an artery with a thin needle and syringe and drawing a small volume of blood.he blood can also be drawn from an arterial catheter. Pulse oximetry plus transcutaneous carbon dioxide measurement is an alternative method of obtaining similar information as well. An ABG is a test that measures the arterial oxygen tension (PaO 2), carbon dioxide tension (PaCO 2), and acidity (pH).

Drawing blood for ABGs And document everything, including the results of the Allen's test, if applicable. Obtaining a blood sample for ABG analysis by percutaneous arterial puncture is a relatively safe procedure. But it's not without risk. Your ability to perform an arterial blood draw safely, confidently, and rapidly, when necessary, could be a true lifesaver. SOURCES. 1.

Hepatic arterial blood flow velocities: assessment by transcutaneous and intravascular Doppler sonography In advanced cirrhosis, even reversal of portal blood flow can occur. Under these conditions, perfusion of the liver depends largely on the hepatic artery. Hepatic arterial blood flow has been investigated extensively by transcutaneous Doppler sonography (TDS). A blunted increase in hepatic arterial resistance after meals has been reported in patients with cirrhosis 56.

CT scan The subject receives an intravenous injection of radiocontrast and then the heart is scanned using a high speed CT scanner, allowing radiologists to assess the extent of occlusion in the coronary arteries, usually in order to diagnose coronary artery disease. Coronary CT calcium scan: also used for the assessment of severity of coronary artery disease. Specifically, it looks for calcium deposits in the coronary arteries that can narrow arteries and increase the risk of heart attack.
