Renal Arterial Doppler Study. Renal Artery Stenosis (RAS) is when the arteries supplying blood to the kidneys narrow down. The renal arteries bring oxygen-rich blood to your kidneys, helping them eliminate waste and excess fluid from your body.

A vascular Doppler ultrasound is used to examine the circulation of your veins and arteries, specifically in your neck, abdomen, arms, and legs. The test bounces high-frequency sound waves off red blood cells to estimate blood flow. A Doppler ultrasound study can be used to diagnose: Blood Clots; Arteriosclerosis; Heart Valve Defects The color Doppler image is dependent on general Doppler factors, particularly the need for a good beam/flow angle. Curvilinear and phased array transducers have a radiating pattern of ultrasound beams that can produce complex color flow images, depending on the orientation of the arteries and veins.

Aims and Objectives: Doppler ultrasound scan is a non-invasive and cheap tool that complements the roles of computed tomography, magnetic resonance imaging and catheter digital subtraction angiography in the screening, diagnosis and follow up of vascular diseases. The Doppler ultrasound technology reflects high-frequency sound waves from red blood cells to detect activity and blood flow. It can recognize conditions like arterial stenosis or occlusion in the superior mesenteric artery and diseases like atherosclerosis or arterial thromboembolic disease.

This exam shows any blockage in the veins by a blood clot or “thrombus” formation. OBJECTIVE: The main objectives of this study were to evaluate the sensitivity and specificity of duplex Doppler ultrasonography in the study of hemodialysis peripheral vascular access dysfunction and to analyze the resistance index and flow in the afferent artery. 2020-07-15 Doppler Assessment: A Practical Guide Elaine Gibson BSc(Hons) DipN, RGN Tissue Viability Vascular Nurse Specialist East Kent University Hospitals Foundation Trust Dr Jon Evans BSc PhD MIET CEng Vascular Business Unit Manager Doppler: L = 1.15 R = 1.11 Recent Study (Davies et al, 2014) Thank You Any Questions. Title: Doppler Assessment What you are most likely scheduled for is “duplex ultrasonography”. Duplex ultrasonography is a non-invasive test that involves both gray-scale images, color doppler, and spectral doppler.
