Although several prophylactic approaches have been proposed for severe reactions, their effects remain unclear. Web21 feb. 2024 · Contrast agents are further classified by their ionic tendency. The presence of a carboxylate functional group (-COO-) produces a net negative charge making the contrast agent ionic, whereas the absence of a carboxylate group infers that the contrast media is non-ionic. Thus, the four basic categories of contrast agents are as follows:
