Ultrasound is the main diagnostic tool in the prenatal detection of congenital abnormalities. The Fetal Medicine Foundation has recognized the importance of this tool by setting up a program of training and certification to help establish high standards of scanning on an international scale. Diagnosis of Fetal Abnormalities: The 18-23-Week Scan provides the basis of learning for the theoretical component of this program. The book is a complete, authoritative clinician's textbook on using ultrasound in the prenatal detection of congenital abnormalities. It summarizes the prevalence, etiology, prenatal sonographic features and prognosis for both common and rare fetal abnormalities.
