This is the third edition of a very successful book that originally emerged from the work of a committee set up by the European Society of Urogenital Radiology in 1994 to consider the safety of contrast media used for diagnostic imaging. The new edition not only fully updates the previous edition, but also includes new chapters on complex topics such as pediatric issues and practical aspects of off-label contrast media use. Comprehensive consideration is given to the many different safety issues relating to iodine-based contrast media, gadolinium-based contrast media, microbubbles for ultrasound, and barium sulfate. The text includes chapters on both acute and delayed non-renal adverse reactions and on renal adverse reactions. All of the questions frequently raised in radiological practice are addressed. This book, presented in a handy, easy-to-use format, provides an invaluable, unique, and unparalleled source of information. von Thomsen, Henrik S.
