The most frequently asked questions that confront the fetal medicine trainee/expert on a daily basis are "Is the finding real or merely an artifact?" and "Is the diagnosis correct?". However, to be able to find the description of an abnormal ultrasound finding in a textbook, one generally has to search by the definite diagnosis, which has not been done as yet. This uneasy feeling was the first factor that directed the layout of Ultrasound of Congenital Fetal Anomalies: Differential Diagnosis and Prognostic Indicators, Second Edition. Copiously illustrated, the book displays fetal anomalies by scanning view and descriptions of all major ultrasound planes, detailing what can be considered a normal view and what cannot. See What's New in the Second Edition: * Early detection of fetal anomalies (1214 weeks) * Ultrasound in fetal infections and in twins * The nuchal translucency issue, the newest intracranial translucency as well as the range of congenital anomalies detectable at this gestational age * Expanded coverage of heart anomalies, including arrhythmias and early fetal echocardiography The author's mission continues to be to provide guidance on how to quickly recognize and diagnose congenital fetal anomalies, beginning at the beginning with ultrasound sigh all the way through to final diagnosis.
