Doppler ultrasound examination of uterine arteries on the day of oocyte retrieval in patients with uterine fibroids undergoing IVF.
BACKGROUND There is no consensus as to whether uterine fibroids have any adverse effects on the outcomes of assisted reproduction treatment. This prospective study compared implantation/pregnancy rates of women with and without fibroids undergoing IVF-embryo transfer and measured uterine blood flow indices of the fibroid group. METHODS Patients who had fibroids that, during transvaginal scann...
متن کاملStudy of the cardiac arrhythmias by the ultrasonic Doppler method.
The Doppler tracing is a sensitive method for depicting movement of the heart wall, valves, and blood flow. This communication reports the authors' experience with the Doppler method in normal persons and patients with various cardiac arrhythmias. Three main components are recognized in the Doppler tracing: the presystolic component, a; component v, due to systolic movement of the ventricles; a...
متن کاملUltrasonic colour Doppler imaging.
Ultrasonic colour Doppler is an imaging technique that combines anatomical information derived using ultrasonic pulse-echo techniques with velocity information derived using ultrasonic Doppler techniques to generate colour-coded maps of tissue velocity superimposed on grey-scale images of tissue anatomy. The most common use of the technique is to image the movement of blood through the heart, a...
متن کاملContinuous wave ultrasonic Doppler tomography.
In continuous wave ultrasonic Doppler tomography (DT), the ultrasonic beam moves relative to the scanned object to acquire Doppler-shifted frequency spectra which correspond to cross-range projections of the scattering and reflecting structures within the object. The relative motion can be circular or linear. These data are then backprojected to reconstruct the two-dimensional image of the obje...
متن کاملUterine Contraction Modeling and Simulation
Building a training system for medical personnel to properly interpret fetal heart rate tracing requires developing accurate models that can relate various signal patterns to certain pathologies. In addition to modeling the fetal heart rate signal itself, the change of uterine pressure that bears strong relation to fetal heart rate and provides indications of maternal and fetal status should al...
