This third edition of Pediatric Urogenital Radiology has been thoroughly updated to take account of the recent advances in the imaging and treatment of pediatric nephro-urologic disorders that have been achieved over the past years. Several new chapters have been included on topics such as the role of ultrasound and MRI for urogenital imaging in the fetus and the use of contrast media in childhood. Other chapters have been extensively revised or rewritten, while information that continues to be pertinent has been retained. The book describes in detail all aspects of pediatric urogenital radiology. It is written primarily from the point of view of the radiologist, but also includes essential clinical information from and for the pediatrician, pediatric surgeon, and urologist. It is specifically designed to aid the clinician in making decisions on imaging management and to help the radiologist to understand the clinical background and needs.
