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...

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 ...

results the mean age was 45.6 ± 13.1 (24 to 74 ) years. twenty-two were normal responders [considered as non-organic causes (37.3% of all patients)], 27 were classified as venous leakage, eight had arterial insufficiency and two were mixed type. maximum psv occurred before the fifth minute in 47 patients (92.2%). eight patients completed all phases of erection in the first 5 minutes. we defined...

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 ...

conclusion for more precise prediction of successful aavf maturation after spta, short-term follow-up doppler ultrasonography (< 2 weeks) was useful. if the asr was < 0.7 or if residual stenosis was ≥ 30%, immediate repeat spta is recommended. results the technical and clinical success rates were both 94.9% (56/59); the mean asr was 0.84. an asr of ≥ 0.7 and no significant residual stenosis (< ...

background: stroke is a multifactorial disorder, the most common cause being arterial occlusion. transcranial doppler ultrasonography (tcd) is a common non-invasive method available for assessment the arterial blood flow of the brain. objective: assessment the hemodynamic parameters of cerebral arteries, using tcd device in patients suffering ischemic stroke. materials and methods: this descrip...

background and aims. although salivary gland tumors are not very common, early diagnosis and treatment is crucial because of their proximity to vital organs, and therefore, determining the efficacy of new imaging procedures becomes important. this study aimed to evaluate the efficacy of magnetic resonance imaging (mri) and color doppler ultrasonography parameters in the diagnosis and differenti...
