MRI contrast agents
MRI contrast agents have become an indispensable part of contemporary magnetic resonance imaging. Although MRI was initially hoped to provide a means of making definitive diagnoses without administering contrast media, it has been found that the addition of contrast agents in many cases improves sensitivity and/or specificity.
History
Paul Lauterbur and his associates were the first to demonstrate the feasibility of using paramagnetic contrast agents to improve tissue discrimination in MRI .
Contrast agents
Contrast agents can be grouped in many different ways. One way is to consider them according to the compartments in which they distribute.
- gastrointestinal MRI contrast agents
- intravenous MRI contrast agents
- intravascular (blood pool) MRI contrast agents
- tumor-specific MRI contrast agents
- hepatobiliary MRI contrast agents
- reticuloendothelial MRI contrast agents
- MRI contrast agent safety
