This easy-to-understand pocketbook in the highly respected Clark's stable of diagnostic imaging texts is an invaluable tool for sonographers in training and in practice, and for midwives, obstetricians, radiologists and other ultrasound practitioners, providing practical guidance on obstetric ultrasound procedures, summarising current relevant literature. Following an initial review of the principles of ultrasound and machine settings for image optimisation, the book focuses on the scans undertaken as a pregnancy progresses, from the routine booking and fetal anomaly scan to additional scans that will be undertaken as needed in the 3rd trimester. An overview of fetal anomalies, with some detail of the commoner ones that are diagnosable at the booking or anomaly scan, is included and material is accompanied throughout by practical tips about how to avoid errors and artefact. Written by specialists in obstetric ultrasound under the direction of the Clark's series editor, each chapter is abundantly illustrated and contains details of patient preparation, imaging technique and image acquisition. Current clinical practice guidelines are used to incorporate the best available evidence for the imaging and management of patients.
