    Abstract

    This chapter focuses on the categorization of magnetic resonance imaging (MRI) contrast agents, enhancement and pharmocokinetic properties of MRI contrast agents, toxicities and complications of administrations of MRI contrast agents, and practical guidelines for administration of MRI contrast agents. MRI contrast agents are classified into three main types: (1) Gadolinium-based contrast agents (GBCAs), (2) iron-based contrast agent, and (3) manganese-based contrast agents. GBCAs are overwhelmingly the most commonly used MRI contrast agents. They are essential for the detection and characterization of tumors, detection of inflammation and fibrosis, assessment of organ perfusion, and delineation of vessels and related vascular pathologies. GBCAs are generally considered to have no nephrotoxicity at approved dosages for MRI. Based on the stability of GBCAs and incidence of nephrogenic systemic fibrosis (NSF) associated with specific GBCAs, they were classified into three groups: high-risk, intermediate-risk, and low-risk agents.
