Dynamic ultrasound-based fetal assessment: the fetal biophysical profile score

The advent of ultrasound fetal imaging and the evolution of dynamic imaging (real-time) methods have opened great new vistas in which fetal responses can be monitored with remarkable precision and clarity. Contained within this new wealth of information may lie the key to direct determination of the fetus at risk for death or injury in utero. Consideration of fetal activities so plainly recognized by conventional dynamic ultrasound methods and an assessment of fetal environment appear to be integral parts of this process. It is reasonable to assume that composite assessment by the dynamic ultrasound-based PBS will remain a valuable adjunct in caring for the high-risk fetus.
