In 1994 the European Society of Urogenital Radiology (ESUR) set up a committee to consider the safety of the contrast media used for diagnostic imaging. Since then, the committee has questioned members, reviewed the literature, proposed guidelines, and discussed these proposals with participants at the annual symposia on urogenital radiology. This book represents the end result of this work. Each topic has been updated by individual members of the committee. The many different safety issues relating to the diverse contrast media: iodinated contrast media, barium contrast media, MR contrast media (both gadolinium-based extracellular and organ-specific) and ultrasound contrast media are comprehensively covered. The text includes chapters on the prevention and treatment of both acute and delayed non-renal adverse reactions as well as renal adverse reactions. Finally the official ESUR guidelines agreed upon by the whole committee are included. The book offers an invaluable, unique and unparalleled resource for safety issues related to contrast media. .
