med.usyd.edu.au Background Patent ductus arteriosus (PDA) in preterm infants is often assessed with echocardiographic parameters, especially colour Doppler ductal diameter and pulsed Doppler flow ...

The PDA shunt flow was identified from four Doppler patterns, and the closed pattern of a closed duct was also presented. Clinically significant PDA was diagnosed when there was colour Doppler ...

Both of these are confounded when there is an atrial shunt, hence limiting the use of relative ventricular output as a measure of PDA significance. This shows the measurement of the color Doppler ...

This work transforms rudimentary radio frequency (RF) data into basic color Doppler and power Doppler data, as would be displayed on conventional ultrasound devices in clinical practice. This code ...
