vertebrobasilar insufficiency is the cause of cerebrovascular accidents in 20% of cases. there are few reports regarding spectral doppler indices (sdis) of vertebral arteries (vas) normal blood flow. the objective of this study was to provide basic reference data about sdis of vas normal blood flow separately and in comparison with internal carotid arteries (icas) and common carotid arteries (c...

Synovial vascularization in metacarpophalangeal joints of a patient with rheumatoid arthritis treated with leukocytapheresis (LCAP) was evaluated by Doppler sonography. After the treatment with LCAP, evaluation with American College of Rheumatology core set showed improvement, and the levels of C-reactive protein and serum amyloid A protein decreased. Power Doppler sonography demonstrated a red...

conclusion gray scale sonography in combination with doppler sonography could be a trustworthy technique in differentiating metastatic lymph nodes from reactive ones. although, circulation pattern had a higher diagnostic accuracy in the present study, combination of sonographic characteristics could be more beneficial in differentiating metastatic cervical nodes from reactive ones. results the ...

In recent years, the use of Doppler ultrasound sonography for the diagnosis of atherosclerosis has increased. However, parameters provided by the commercially available Doppler ultrasound units are inadequate to compete with the gold standard method, catheter angiography. Therefore, developing a new method based on Doppler ultrasound sonography remains a hot topic among researchers. In this stu...

We evaluated the effectiveness of color and spectral Doppler examination of the ovarian vasculature flow, using transvaginal sonography (TVS) in 65 women prior to laparoscopy due to suspected ovarian torsion. There were 15 cases of ovarian torsion. In all of them, a pathology was detected by the color and spectral Doppler examination. Of the 50 patients without torsion at laparoscopy, one had a...

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 ...

OBJECTIVE The aim of this study was to compare the effectiveness of transvaginal power Doppler sonography with spectral Doppler analysis as an aid in preoperatively distinguishing primary ovarian carcinoma and metastatic carcinoma to the ovary (Krukenberg tumors). METHODS Fifty women with ovarian disease were preoperatively examined with transvaginal power Doppler sonography. Six basic parame...

detection of lymph nodes (lns) involvement by various pathological processes has great therapeutic and prognostic implications. the purpose of this study was to evaluate the usefulness and accuracy of triplex sonography (gray scale, color mapping and spectral doppler) in differentiating benign from malignant cervical lns. we used triplex sonography to evaluate 120 lns in 50 patients. the gray s...
