This is the only book of its kind in prenatal diagnosis that details the most common sonographically detectable fetal syndromes. It has an easy-to-follow approach of using lists and patterns of malformations to generate a differential diagnosis of the possible syndrome involved. The reader is then led to the more detailed description of each syndrome to determine the exact final diagnosis. The new edition incorporates 3D ultrasound throughout the book, as well as 20 syndromes not previously covered.
