Doppler colour flow imaging of fetal intracerebral arteries relative to fetal behavioural states in normal pregnancy.
In 14 normally developing term fetuses, the relationship between the blood flow velocity waveforms at cerebral arterial level (internal carotid artery, anterior, middle and posterior cerebral artery) and fetal behavioural states was studied using Doppler colour flow imaging. Behavioural state dependent changes in absolute flow velocities occurred in all vessels, except for the middle cerebral a...

15 صفحه اولthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Evaluation of normal fetal ductus venosus using B-flow imaging with spatiotemporal image correlation and traditional color Doppler echocardiography.
OBJECTIVE To explore the feasibility of using four-dimensional echocardiography with B-flow and spatiotemporal image correlation (4DBF-STIC) imaging technology to detect fetal ductus venosus (DV), and establish the normal reference range for the ductus venosus diameter at 18-40 weeks gestation. METHODS This was a prospective observational study to detect the DV in 354 normal fetuses at 18-40 ...
متن کاملEffects of Dexamethasone on Fetal Doppler Indices
Objective: To assess the impacts of dexamethasone given to the mother on fetal Doppler flow velocity waveforms of both umbilical and fetal middle cerebral arteries in pregnancies with normal fetoplacental vascular resistance. Study Design: Prospective Study. Patients and Methods: Pregnant women between 28 weeks and 34 weeks gestation at risk of preterm labour, Preterm birth was anticipated on t...
