Safety of magnetic resonance imaging contrast agents

Many of the MR examinations performed in the World each year are accompanied by administration of one of these frequently used intravenous contrast agents: Magnevist, Omniscan, and ProHance. Accordingly, MR practitioners must understand the basic pharmacokinetics, side effects, and the potential for adverse events for these contrast agents. Additionally, MR practitioners must know how to manage side effects and adverse events that may occur in association with the administration of contrast agents. Notably, the use of MR imaging contrast agents in special patient populations must be understood. This article discusses each of these important issues. (C) 1999 Wiley-Liss, Inc.
