Opis

The aim of this work was not an exhaustive review of all pediatric echo graphic problems but a presentation of our daily experience with ultrasonography in pediatric practice. Several teams of pediatric radiologists from France and Belgium have combined their experiences to produce a practical book. The different authors have been chosen for their specific experience and their special area of work. The different chapters express therefore personal opinions. Unresolved questions are posed and ultrasonographic examinations are used in the diagnosis of different diseases, while the discoveries and ideas of the individual authors are described. Some fields are not included, such as echocardiography. Gabriel Kalifa Contents Chapter 1.
