We present a case of an internal carotid web, detected on duplex ultrasound and confirmed by CT angiography. To our knowledge, this is only the third reported ultrasound case in the imaging literature. This vascular abnormality can cause a clinically significant carotid stenosis and is a risk factor for recurrent embolic cerebrovascular events. Due to small size and poor awareness among radiolo...

OBJECTIVE To evaluate the diagnostic value of prostate-specific antigen density (PSAD) and the appropriate cutoff for the detection of prostate cancer. MATERIAL AND METHOD Between January 2008 and March 2011, 292 men with PSA levels between 4 and 10 ng/mL underwent transrectal ultrasonography (TRUS) with prostate biopsy. The diagnostic value of PSA levels and PSAD were compared using receiver...

OBJECTIVES Duplex ultrasound investigation has become the reference standard in assessing the morphology and haemodynamics of the lower limb veins. The project described in this paper was an initiative of the Union Internationale de Phlébologie (UIP). The aim was to obtain a consensus of international experts on the methodology to be used for assessment of veins in the lower limb by ultrasound ...

INTRODUCTION Duplex ultrasound facilitates bedside diagnosis and hence timely patient care. Its uptake has been hampered by training and accreditation issues. We have developed an assessment tool for Duplex arterial stenosis measurement for both simulator and patient based training. METHODS A novel assessment tool: duplex ultrasound assessment of technical skills was developed. A modified dup...

Temporal artery is superficially exhibited and easily traumatized. Rarely, a minor and blunt trauma, especially in elderly who are under anticoagulants, can cause a pseudoaneurysm. Diagnosis should be based, primarily, on history and physical examination and secondarily on duplex ultrasound scanning which will lead to confirmation and preoperative planning. The therapeutical plan consists of su...

Purpose: There is no information about gastric blood flow in children with chronic gastritis. In this study, we aimed to evaluate hemodynamic changes of the celiac artery by trans-abdominal duplex Doppler ultrasonography, Materials and Methods: We examined 64 ultrasonography. 36 (group 1) active gastritis (diagnosed endoscopy histology) 28 healthy 2) were included study. Children classified aga...

in this paper using strongly duplexes we introduce a new class of (semi)hypergroups. the associated (semi)hypergroup from a strongly duplex is called duplex (semi)hypergroup. two computer programs written in matlab show that the two groups $z_{2n}$ and $z_{n}times z_{2}$ produce a strongly duplex and its associated hypergroup is a complementary feasible hypergroup.

STUDY OBJECTIVE Compression ultrasonography of the lower extremity is an established method of detecting proximal lower extremity deep venous thrombosis when performed by a certified operator in a vascular laboratory. Our objective is to determine the sensitivity and specificity of bedside 2-point compression ultrasonography performed in the emergency department (ED) with portable vascular ultr...
