The Society of Radiologists in Ultrasound convened a multidisciplinary panel of experts in the field of vascular ultrasonography (US) to come to a consensus regarding Doppler US for assistance in the diagnosis of carotid artery stenosis. The panel's consensus statement is believed to represent a reasonable position on the basis of analysis of available(More)

Abdominal aortic aneurysms occur in as much as 2–3% of the population, and their rupture produces a mortality rate of 78–94% (1), causing 15,000 deaths per year in the U.S. alone. As an investigation into the mechanical factors that lead to aneurysm rupture, flow field measurements are presented for steady flow through a range of aneurysm sizes and Reynolds(More)
Doppler sonography, combining high-resolution imaging and Doppler spectrum analysis, has proven to be the best choice for safe, noninvasive, low-cost screening for the etiology of stroke. With high-resolution imaging, plaque can be characterized relative to the risk for intraplaque hemorrhage, thought by many to be the precursor of plaque ulceration. Using(More)
PURPOSE To evaluate power Doppler imaging as a possible screening examination for carotid artery stenosis. MATERIALS AND METHODS In the principal pilot study, a prospective, blinded comparison of power Doppler imaging with duplex Doppler imaging, the reference-standard method, was conducted in 100 consecutive patients routinely referred for carotid artery(More)
OBJECTIVE Continuous quality improvement is being advocated as a process that, if adopted, could lead to greater efficiency and productivity in medical institutions. To determine whether continuous quality improvement techniques could be effective in radiology departments, we undertook a model project that sought to improve our ability to interpret(More)
A complex duplex carotid evaluation involves high resolution imaging and characterization of the carotid plaque as well as quantitative Doppler spectral analysis to determine the presence and degree of flow restriction. Each of the components of the examination is essential to evaluate the carotid arteries adequately for the presence of disease. Both of(More)
OBJECTIVE To describe the importance of obtaining erect views when evaluating the celiac artery with sonography. METHODS Two patients had duplex and color flow Doppler sonographic evaluations of the celiac artery, including inspiration, expiration, and erect views. RESULTS Both patients had elevated celiac artery velocities with inspiration and(More)
OBJECTIVE Our objective was to quantitatively assess the value of early posttransplantation hepatic artery resistive indexes in predicting vascular and nonvascular complications in adult orthotopic liver transplant (OLT) patients. MATERIALS AND METHODS Between 1999 and 2001, 110 consecutive adults received grafts. Doppler sonographic graft evaluations(More)
By careful evaluation of the sonographic characteristics of carotid plaques, two patterns can be identified: a homogeneous pattern containing uniform echoes corresponding to dense fibrous tissue and a heterogeneous pattern containing mixed echoes and anechoic areas that represent intraplaque hemorrhage pathologically. A prospective study was conducted of 50(More)
