The use of gadolinium-based contrast agents (GBCAs) to diagnose abnormalities in MR images has become one of radiology’s hottest topics, and it even made national news after a recent lawsuit filed by Chuck Norris and his wife, Gena. According to a new study published in Radiology, a manganese-based contrast agent, manganese-N-picolyl-N,N’,N’-trans-1,2-cyclohexenediaminetriacetate (Mn-PyC3A), could be on its way to replacing GBCAs in some advanced imaging exams.
