Course Description
Gadolinium-based contrast agents (GBCAs) increase the diagnostic sensitivity of magnetic resonance imaging (MRI) by shortening the T1 relaxation time of certain tissues, improving the detection and monitoring of conditions including cancer and vascular and neurological diseases. While GBCAs have an excellent safety profile, their use still requires careful consideration of patient risk factors, potential adverse reactions, and rare long-term renal complications. Safe administration depends on MR personnel who understand GBCA chemistry and risk classification, appropriately screen patients, select the correct contrast agent and dose, and recognize and manage a patient's adverse events when they occur. This course provides MR personnel with the foundational knowledge needed to support safe GBCA use in everyday clinical practice. It begins with a review of T1 relaxation physics and how gadolinium enhances the MR signal, followed by GBCA chelate chemistry, structural classification, and risk grouping. Patient evaluation and GBCA selection are also covered, as well as a discussion of appropriate questions to ask in order to screen patients for risk factors and considerations for special populations such as pediatric, pregnant, or breastfeeding patients. The course concludes with an introduction of communication, documentation, and emergency response protocols, highlighting how each member of the MR team contributes to safe GBCA administration.

Learning Objectives
After reviewing the activity, the participant should be able to:

• EXPLAIN how gadolinium-based contrast agents (GBCAs) enhance MRI signal and identify their clinical indications for use.
• DIFFERENTIATE GBCAs by chelate chemistry, structural classification, and risk group.
• EVALUATE patients for GBCA contraindications and risk factors to select the appropriate GBCA type and dose.
• PRACTICE communicating with the patient and MR team members regarding contrast media administration, documentation, and emergency response protocols.
