results color doppler usg had a sensitivity of 95% and specificity of 98% in diagnosis of arterial injury. positive and negative predictive values of doppler usg were 92.5% and 94.2%, respectively. conclusions color doppler usg can be used as a reliable modality with acceptable sensitivity and specificity values to screen hemodynamically stable patients with limb trauma suspicious for arterial ...
background: although color doppler ultrasonography (cdus) is useful in the diagnosis of various diseases of the head and neck, flow signals in oral malignant masses are less studied; hence the present study assesses the usefulness of color doppler ultrasonography in quantifying oral squamous cell carcinoma (oscc) vascularization. in addition, we determine the hemodynamic parameters by spectral ...
three-dimensional color doppler ultrasonography is a new technique to evaluate the pattern of blood vessels. this study was performed to assess the feasibility of this method in evaluation of kidney vasculature pattern in dogs. in this paper, visualization of the renal, interlobar, arcuate, and interlobular arteries and veins using 3d color doppler ultrasonography in dogs is shown and the techn...

doppler ultrasound can provide important information about vascular problems through the analysis of blood flow wave-form. the purpose of this study was obtaining the normal images of color doppler and estimation of blood flow velocity parameters of femoral artery in rabbits. left and right femoral arteries of 8 healthy adult new zealand rabbits were evaluated. color and spectral doppler images...
Background: Diagnostic ultrasound has been used to detect human disease especially fetus abnormalities in recent decades. Although the harmful effects of diagnostic ultrasound on human have not been established so far, several researchers showed it has had bioeffects in cell lines and in experimental animals. Three-dimensional (3D), four-dimensional (4D), and color Doppler sonography are new te...
background the behcet disease is a multisystemic disease with involvement of vessels. objectives our aim is to evaluate the frequency of carotid artery disease in asymptomatic carotid artery involvement in patients with behcet disease and compare the results with a control group. patients and methods fifty patients with behcet disease who were asymptomatic for any vascular involvement and 50 he...
Background In patients with abnormal uterine bleeding, transvaginal ultrasound (TVS) is the first-line diagnostic approach to exclude endometrial pathology. If a thickened endometrium suggests endometrial pathology, sonohysterography, office hysteroscopy or dilatation and curettage are the second-line tests preferred, depending on availability and on the suspected pathology, to exclude malignan...
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...
