Gadolinium-based contrast agents: A comprehensive risk assessment.
Gadolinium-based contrast agents (GBCAs) have been used in magnetic resonance imaging (MRI) since the 1980s and are now administered in up to 35% of all MRI examinations. While GBCAs were initially felt to carry minimal risk, the subsequent identification of GBCAs as the key etiologic factor in the development of nephrogenic systemic fibrosis (NSF) has raised concerns about the broader health i...
متن کاملHepatobiliary MR imaging with gadolinium-based contrast agents.
The advent of gadolinium-based "hepatobiliary" contrast agents offers new opportunities for diagnostic magnetic resonance imaging (MRI) and has triggered great interest for innovative imaging approaches to the liver and bile ducts. In this review article we discuss the imaging properties of the two gadolinium-based hepatobiliary contrast agents currently available in the U.S., gadobenate dimegl...
متن کاملSynthesis and Application of New Gadolinium-Porphyrins as Potential MR Imaging Contrast Agents for Cancer Detection in Nude Mice
Two new potential magnetic resonance imaging contrast agents, Gd-hematoporphyrin (Gd-H) and Gd-tetra-carboranylmethoxyphenyl-porphyrin (Gd TCP), were synthesized and applied to nude mice with human melanoma (MM 138) xenografts. These agents showed a high relaxivity because of their greater potential to coordinate water molecules. The reduction of T1 relaxation times of 16 and 21% was observed i...
متن کاملNo Association between Gadolinium-Based Contrast Agents and Development of Nephrogenic Systemic Fibrosis: a Case Study
Nephrogenic systemic fibrosis (NSF), previously known as nephrogenic fibrosing dermopathy, is an emerging systemic fibrosing disorder that develops in the setting of renal insufficiency. Nephrogenic fibrosing dermopathy (NFD) is a fibrosing condition of the skin which shows an increased number of dendritic cells, fibroblasts and thickened collagen fibers resembling scleromyxedema. It is charact...
متن کاملIncidence and severity of acute adverse reactions to four different gadolinium-based MR contrast agents.
PURPOSE Differences in acute adverse reactions to different gadolinium (Gd)-based contrast agents have not been thoroughly evaluated. We investigated the relationships among the incidence and severity of acute adverse reactions, backgrounds of patients, and 4 types of different Gd-based contrast agents (gadopentetate dimeglumine, gadoteridol, gadoterate meglumine, and gadoxetate disodium). MA...
