The objective of this study was to evaluate the importance of Doppler ultrasonography in diagnosing renal artery stenosis in transplanted kidneys using angiography as the accepted gold standard. Fourteen kidney graft recipients with clinical severe hypertension, impaired renal function, or both had their renal artery blood flow studied by Doppler ultrasonography before angiography. Seven patien...

conclusions the aspirates from the hypovascular and hypervascular sites of solid nodules are complementary and should be performed consecutively. results when only hypervascular site was used, adequate sampling was limited to 65% of the cases. when both sites were evaluated together, overall adequate sampling was 91%. adding a sample from the hypervascular site to hypovascular aspirate increase...

background endothelial injury is a well-known complication in chronic kidney disease (ckd) and hemodialysis. one of the sites in which early vascular changes may be detected is the retina. of course, these flow changes may not be detected in ophthalmologic exams, but it seems that color doppler sonography of retinal arteries may be helpful in these cases. objectives in previous studies on ckd p...

We assessed the potential of 2-MHz pulsed-wave transorbital Doppler ultrasonography to delineate the role of the ophthalmic artery as a source of collateral cerebral blood supply by comparing oculopneumoplethysmography, transorbital Doppler ultrasonography, periorbital continuous-wave Doppler ultrasonography, and transcranial Doppler ultrasonography in 25 patients with unilateral internal carot...

BACKGROUND/AIM It is highly appreciated to provide exact data on vascular invasion of pancreatic carcinoma relying as much as possible on non-invasive diagnostic procedures. Color Doppler ultrasonography has been proven as an efficient method for clinical staging of pancreatic carcinoma essential for therapeutic decisions. The aim of this study was to provide an analysis of the sensitivity and ...

introduction: deep vein thrombosis (dvt) is a major cause of morbidity and mortality in intensive care unit (icu) patients despite use of prophylactic anticoagulant therapy. the aim of the present study was to determine the incidence of dvt among medical and surgical icu patients. methods: in this cross sectional study, patients older than 18 years who were hospitalized in the icu of imam hosse...

background: the aim of this study is to determine the frequency of intracranial artery stenosis in patients with acute ischemic stroke in iran. methods: a total of 169 patients with acute ischemic stroke were eligible to participate and were enrolled in this study from january 2012 to february 2013. all the patients were admitted to the nemazee ‎hospital, affiliated to shiraz university of medi...

background: the recent developments in tissue doppler imaging (tdi) now more than ever permit the quantification of the myocardial function. in the current systems, tissue tracking or displacement curves are generated from color tissue doppler data through the instantaneous temporal integral of velocity-time curves. methods: the purpose of the present study was to assess regional myocardial dis...

Objective- Analysis of the PSV (peak systolic velocity), EDV (end diastolic velocity) and RI (Resistant Index) in external ophthalmic and the long ciliary ophthalmic arteries in the cat by pulse Doppler. Design- Descriptive study Animals- 12 short haired “Tomcats” weighted about 3.9± 0.9 Kg no e general and optic disease in clinical, paraclinical and ophthalmoscopic examinations. Pr...

Penile Doppler ultrasonography is a high-performing, noninvasive or minimally-invasive imaging modality that allows the depiction of the normal anatomy and macroscopic pathologic changes in real time. Moreover, functional changes in penile blood flow, as seen in erectile dysfunction (ED), can be analyzed using color Doppler ultrasonography (CDUS). This review article describes the normal sonogr...
