[Comparison of the results of umbilical artery velocimetry obtained by pulsed Doppler and continuous Doppler].
Doppler assessment has become the fashion in obstetric screening at present and this is absolutely justified in view of the quality of the information that is obtained. The authors have tried to assess the two methods of analysing the blood flow through the umbilical artery by using pulsed Doppler and continuous Doppler techniques. They have used a fairly new statistical method (differential). The authors have found that the methods are interchangeable. They did this on 32 patients who on the same day had pulsed and continuous Doppler tests and they used Pourcelot's placental resistance technique. These observations show that consistent diagrams which are equivalent to one another are obtained by the two methods and they can be used economically.
