Doppler Ultrasound
The Doppler shift principle has been used for a long time in foetal heart rate detectors. Further development sin Doppler ultrasound technology in recent years have enabled a great expansion in its application in obstetrics, particularly in the area of assessing and monitoring the well being of the foetus, its progression in the face of intrauterine growth restriction, and the diagnosis of cardiac malforamtions.
Doppler ultrasound is presently most widely employed in the detection of foetal cardiac pulsations and pulsations in the various foetal blood vessels. The ‘Doptone’ foetal pulse detector is a commonly hand held device to detect foetal heartbeat using the same Doppler principle.
Blood flow characteristics in the foetal blood vessels can be assessed with Doppler flow velocity waveforms. Diminished flow, particularly in the diastolic phase of a pulse cycle is associated with compromise. Various ratios of the systolic to diastolic flow are used as a measure of this compromise. The blood vessels commonly interrogated include, the umbilical artery, the aorta, the middle cerebral arteries, the uterine arcuate arteries, and the inferior vena cava.
The use of colour flow mapping can clearly depict the flow of the blood in foetal blood vessels in a realtime scan, the direction of the flow being represented by different colours. Colour Doppler is particularly indispensible in the diagnosis of foetal cardiac and blood vessel defects, and in the assessment of the hemodynamic responses to foetal hypoxia and anaemia.
A more recent development is Doppler angiography. It uses amplitude information from Doppler signals rather than flow velocity information to visualise slow flow in smaller blood vessels. A colour perfusion like display of a particular organ such as the placenta overlapping on the 2d image can be very nicely depicted. Doppler examinations can be performed abdominally and via the transvaginal route. The power emitted by a Doppler device is greater than that used in a conventional 2d scan. Its use in early pregnancyis therefore cautioned.
Doppler facilities are generally an integral part of modern ultrasound scanner. You do not need to go to another machine for Doppler investigations.
