background: as delay in diagnosis of ectopic pregnancy is directly associated with increasing mortality, it studying the high sensitivity and specificity of transvaginal color doppler sonography as the most preferred imaging method with the most accurate and rapid diagnosis results seems to be necessary. therefore, this study aims to evaluate the diagnostic value of transvaginal color doppler s...

background: we conducted our study on 1110 patients with breast masses in order to investigate different aspects of power doppler sonography (pds) for differentiating between benign and malignant breast lesions and their prognostication. materials and methods: this study was conducted on the women who were referred to the sonography units of university hospitals for breast sonography and had a ...

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: the drug-eluting stent (des) decreases the rate of coronary restenosis and re-obstruction. the aim of this study was to assess prospectively the effectiveness of the new generation des on the left ventricular (lv) systolic and diastolic functions in patients with isolated severe proximal left anterior descending (lad) coronary artery stenosis. methods: a prospective study was conduc...

introduction: doppler ultrasonography (dus) is the most preferable method for screening of carotid artery disease in patients undergoing cabg. the purpose of this study was to investigate the frequency of carotid artery disease and determine the relation between known risk factors of atherosclerosis and rate of carotid artery narrowing in order to identify high-risk groups among patients schedu...

purpose: to assess orbital color doppler ultrasonography (cdu) parameters of patients with manifest hyperopia in comparison to the emmetropes methods: forty eyes of 40 patients presenting with manifest hyperopia were included into the study. forty eyes of 40 emmetropes healthy volunteers also were examined as the control group. we have evaluated ophthalmic artery (oa), central retinal artery (c...

ndometrial vasculature has been shown to play an important role in the early endometrial response to the implanting blastocyst, and vascular changes may contribute to uterine receptivity . the aim of this study was to investigate the role of endometrial and subendometrial vascularity and thickness in uterine receptivity in infertile women treated with assisted reproductive technologies (art). a...

conclusions our study showed that ultrasonography findings can be a good predictor of sperm parameters in patients with varicocele. results the semen analysis parameters, including semen volume and sperm morphology, count, and motility, significant correlations with the diameter of the varicocele vein but were not correlated with testes size. in addition, the patients with reflux of longer than...

conclusions pci was accompanied by some improvement in left atrial deformation indices as assessed by tissue doppler imaging. revascularization can, therefore, improve patient outcome. results regarding changes in left trial functional parameters after pci, those such as the strain of the septal wall and the anterior and inferior walls and the strain rate of the anterior and lateral walls signi...

this is retrospective double-blind research, which was carried out in imam khomeini hospital in order to study the accuracy of color doppler ultrasonography for detecting the site and grade of stenosis in cervical carotid artery. 40 patients with mean age of 62 years studied with color doppler before dsa angiography. the most common sites of stenosis were left internal carotid (39.5%) and right...
