Renal ultrasonography using duplex technique of a normal adult kidney, with the estimation of the systolic velocity (Vs), the diastolic velocity (Vd), acceleration time (AoAT), systolic acceleration (Ao Accel) and resistive index (RI). Red and blue colors in the color box represent flow towards and away from the transducer, respectively.

Optimal depth and focus setting for carotid (Duplex) ultrasound/sonography at a depth of 2,5cm. Note that the common carotid artery is seen “full screen” - still the depth is set in such a way that structures approximately 1 cm posterior to the common carotid artery are still visible. The focus point is at the level of the carotid artery. Duplex ultrasound is an evolving technology that allows the assessment of volumetric blood flow in the carotid and vertebral arteries during a range of interventions along the spectrum of health and chronic disease. Duplex ultrasound can provide high-resolution diameter and velocity information in r … Se hela listan på Intravascular ultrasound (IVUS) allows a detailed assessment of the carotid lumen, vessel wall, atherosclerotic plaque, stent dimensions, and expansion as well as its apposition to the vessel wall in 3 dimensions.

Currently, carotid duplex ultrasound is the primary diagnostic tool for the evaluation for ICA stenosis and must be performed by a trained and certified vascular 

The Blended Introduction to Carotid & Peripheral Vascular Duplex/Color Flow Ultrasound Course is specifically designed for busy sonographers, physicians and other medical professionals who need to complete the online course work at their convenience from work, the office, or any mobile device and still obtain the hands-on skills training needed to confidently and competently complete vascular A duplex ultrasound combines: (Traditional ultrasound) This uses sound waves that bounce off blood vessels to create pictures and, (Doppler ultrasound) This records sound waves reflecting off moving objects, such as blood, to measure their speed and other aspects of how they flow. Extracranial cerebrovascular ultrasound evaluation consists of assessment of the accessible portions of the common carotid, external and internal carotid, and the vertebral arteries. A. Scanning Technique All arteries should be scanned using appropriate gray scale and Doppler techniques and prop- Doppler ultrasonography is medical ultrasonography that employs the Doppler effect to generate imaging of the movement of tissues and body fluids (usually blood), and their relative velocity to the probe.By calculating the frequency shift of a particular sample volume, for example, flow in an artery or a jet of blood flow over a heart valve, its speed and direction can be determined and Carotid Ultrasound Carotid Ultrasound (Carotid Doppler, Carotid Duplex) This is safe and painless procedure, where blood flow in the carotid arteries is evaluated with sound waves.

Email AJUM August 2010; 13 (3): 20–22 DIAGNOSTIC ULTRASOUND Fig. 1: Definition of carotid stenosis. Fig. 2: Types of carotid Carotid artery ultrasounds are used to assess the extracranial carotid arteries for the presence of stenosis and to determine the direction of blood flow. The use of carotid artery ultrasound as a diagnostic tool in the evaluation of syncope can be traced to multiple articles from the 1980s. A duplex ultrasound is used in diagnose of an abdominal aneurysm, blood clots, arterial occlusion, venous insufficiency, varicose veins, renal vascular disease, carotid occlusive disease. Like the Doppler ultrasound, this method of testing is completely harmless and can be repeated, as often, as necessary.

Patients were followed up with annual DUS imaging and underwent both ultrasound scans and computed tomography angiography (CTA) at their most recent follow-up visit.
