Purpose: To determine adverse reaction rates in a tertiary care clinical setting after adoption of gadoteridol as the institutional routine magnetic resonance (MR) imaging contrast agent.
Materials And Methods: With institutional review board approval, informed consent waiver, and HIPAA compliance, a prospective observational study of 28 078 patients who underwent intravenous gadoteridol-enhanced MR imaging from July 2007 to December 2009 was performed. Reactions were recorded by technologists who noted types of reactions, method of injection, and treatment.
