Episode 27: Gadolinium Based Contrast Agents (Part 1) - Intro & Safety From The ViewBox

In this episode we discuss Gadolinium-based contrast agents (GBCA) or media (GBCM). Building on previous discussions of MRI safety (Ep9 & 11) and Contrast and Adverse Reactions from Ep 5 & 6, this episode will introduce MRI contrast agents (GBCA or GBCM), their make-up, categories and general safety profiles. m including some of the inherent safety issues that arise from them; the concept of safety zones and its importance; examples of unique safety issues in MRI, and the screening process. Summary of some common GBCA and their trade names includes:
Gadoteridol (ProHance) - Macrocyclic - Nonionic
Gadobutrol (Gadavist) - Macrocyclic - Nonionic
Gadoterate (Dotarem) - Macrocyclic - Ionic
Gadodiamide (Omniscan) - Linear - Nonionic
Gadoversetamide (Optimark) - Linear - Nonionic
Gadobenate (MultiHance) - Linear - Ionic
Gadopentetate dimeglumine (Magnevist) - Linear - Ionic

This is part one of a two-part series on the basics of GBCA.
