I-45: Color Doppler Sonography of Endometrium in Infertility Patients
Background Endometrial receptivity is one of parameters which determine the reproductive outcome in in vitro fertilization programs. A good blood supply towards the endometrium is usually considered to be an essential requirement for implantation. Blood vessels of the endometrium can be detected by transvaginal color and pulse Doppler sonography. Color Doppler assessment permits better visualiz...
متن کاملTwinkling artifact on intracerebral color Doppler sonography.
Transcranial Doppler sonography shows potential as a noninvasive technique for long-term follow-up of treated intracranial saccular aneurysms. This technical note describes a color Doppler artifact related to microcoil architecture that might represent a potential pitfall in transcranial Doppler sonographic evaluation of aneurysmal cavity thrombosis, since it may be wrongly interpreted as resid...
متن کامل[Estimation of renal transplant dysfunction by color Doppler sonography].
BACKGROUND To clarify various conditions in the transplanted kidney, invasive biopsy must be performed in most cases. In this study, we measured blood flow in the transplanted kidney by color Doppler tomography to examine the usefulness of measuring renal blood flow in clarifying various conditions. METHOD Blood flow in the transplanted kidney was measured using peak flow velocity (PFV) and a...
متن کاملCarotid artery disease assessed by color Doppler flow imaging: correlation with standard Doppler sonography and angiography.
Carotid artery disease was assessed in 180 patients by means of color Doppler flow imaging. Color Doppler findings in 360 carotid arteries were compared with the results of standard Doppler sonography, and color Doppler findings in 60 bifurcations were compared with the results of intraarterial angiography. The sensitivity of color Doppler for the detection of carotid disease was 100% when comp...
متن کاملComparision of the Diagnostic values of Doppler Sonography with Fine Needle Aspiration in Thyroid Nodules
Introduction: Thyroid nodules are frequent occurrences, and whenever diagnosed, it is necessary to rule out of malignancy. Valuable diagnostic methods in this field are sonography and fine needle aspiration. In this study while investigating these two methods, we compared them with postsurgical pathologic findings. Materials and methods: This is a cross sectional, descriptive-analytical study. ...
