Color and pulsed Doppler in fetal echocardiography

Fetal Dual Doppler Echocardiography

Dual Doppler echocardiography is a recently developed technique performed using an instrument with two separate sample gates, allowing simultaneous recording of signals from two locations. We describe the use of dual Doppler echo­ cardiography to assess fetal cardiac rhythm. Fetal arrhythmias are common and encountered in 1 to 2% pregnancies. They often resolve spontaneously and do not require ...

Normal Color and Pulsed-Waved Doppler Ultrasonography of Femoral and Axillary Arteries in Dogs

Objective- Obtaining the normal images ofcolor doppler and estimation ofblood flow velocity parametersof femoral and axillary arteries in dog.Design- Descriptive studyAnimals- 7 healthy adult mixed-breed dogs, weighing 14.3 ± 2.8 kg (mean ± SD).Proceudure- Left and right femoral and axillary arteries of hind and forelimbs were evaluated. Colorand spectral doppler images ofthe each artery were o...

Color and power Doppler combined with Fetal Intelligent Navigation Echocardiography (FINE) to evaluate the fetal heart

OBJECTIVE To evaluate the performance of color and bidirectional power Doppler ultrasound combined with Fetal Intelligent Navigation Echocardiography (FINE) in examining the fetal heart. METHODS A prospective cohort study was conducted of fetuses in the second and third trimesters with a normal heart or with congenital heart disease (CHD). One or more spatiotemporal image correlation (STIC) v...
