15 صفحه اولReference ranges for Doppler assessment of uterine artery resistance and pulsatility indices in dichorionic twin pregnancies.
OBJECTIVES To construct reference ranges of uterine artery Doppler parameters against gestation in twin pregnancies and to present charts of the pulsatility index (PI) and resistance index (RI) for clinical use. METHODS This was an observational study of the uterine circulation in 557 women with dichorionic twin pregnancies at 17-38 weeks' gestation. Uterine artery measurements were performed...
متن کاملBlood flow velocity in monocular retinoblastoma assessed by color doppler
OBJECTIVE To analyze the flow of retrobulbar vessels in retinoblastoma by color Doppler imaging. METHODS A prospective study of monocular retinoblastoma treated by enucleation between 2010 and 2014. The examination comprised fundoscopy, magnetic resonance imaging, ultrasonography and color Doppler imaging. The peak blood velocities in the central retinal artery and central retinal vein of tum...
متن کاملFetal Doppler echocardiographic assessment of cardiac blood flow velocity in normal fetuses and in those with congenital heart disease.
Ninety fetal Doppler echocardiographic examinations were performed on 72 normal fetuses and 5 with congenital heart disease [2 pulmonary stenosis (PS), 1 pulmonary atresia (PA), 1 tetralogy of Fallot (TOF) and 1 endocardial cushion defect (ECD)] at 16 to 40 weeks of gestational age. The maximum transmitral (MVMax), transtricuspid (TVMax), transaortic (AVMax) and transpulmonary blood flow veloci...
متن کاملDoppler assessment of fetal aortic isthmus flow in twin
OBJECTIVE The purpose of this study was to investigate the aortic isthmus (AoI) flow difference between larger fetus and smaller fetus of twin; and to evaluate the predictive value of early diagnosis of hemodynamic change in twin growth. METHODS This prospective study on 49 pairs of twin fetuses was performed to obtain AoI blood flow data. Cases with structural or chromosomal abnormalities an...
