MRI Contrast Agents
April 2007
MRI (magnetic resonance imaging) contrast agents, also called paramagnetic agents, are used to help give a clear picture during MRI. MRI is a special kind of diagnostic procedure. It uses magnets and computers to create images or “pictures” of certain areas inside the body. Unlike x-rays, it does not use radiation.
MRI contrast agents are given by injection before or during MRI to help diagnose problems or diseases of the brain or spine. In addition, contrast agents may also be used to help diagnose problems in other parts of the body, such as the bones and joints, breast, liver, soft tissues, and uterus. MRI contrast agents may also be used to diagnose other conditions as determined by your doctor.
