Doppler ultrasound is playing an increasing role in obstetrics, and its applications in screening and the monitoring of high-risk pregnancy are attracting much interest. This is a comprehensive and readable guide to its theory and practice, written by leading experts who have carried out much of the original work in the field. The first section reviews the physics and statistical concepts of Doppler ultrasound, gathering together information not otherwise available to clinicians. Next, it describes the means of acquiring waveforms, and their use in various clinical settings. Practical guidance is given on setting up continuous-wave Doppler equipment in the district general hospital. Finally the book discusses the use of pulsed-wave and color-flow Doppler ultrasound. This detailed work summarizes such areas as the management of fetal cardiac dysrhythmias, the study of neonatal cerebral blood-flow, and the estimation of maternal cardiac output. An outstanding reference source, the book will be essential reading for obstetricians, radiologists, and ultrasonographers, and will be valuable both to those new to the field and those already using a Doppler ultrasound system in perinatal medicine.
