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)
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)
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)
The American Registry of Radiologic Technologists (ARRT) is the largest national, voluntary certification organization for radiologic technologists, with 235,000 registered technologists and an annual examination volume of 20,000 to 25,000. The ARRT's board is appointed by the ACR (four members) and the American Society of Radiologic Technologists (five(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)
PURPOSE To evaluate the role and usefulness of diagnostic ultrasonography (US) in the assessment of hemodialysis access grafts with an intermediate probability of graft malfunction. MATERIALS AND METHODS One hundred forty-seven complete US examinations were performed in 91 patients. Average volume of flow, peak systolic velocity, and diameter of residual(More)
PURPOSE The ACR Commission on Human Resources continues to conduct its annual electronic survey to better understand the present workforce scenario for radiologists. METHODS The Practice of Radiology Environment Database was used to identify group leads, who were asked to complete an electronic survey developed by the Commission on Human Resources. The(More)
