Contrast Exams

Contrast agents are used during MRI to enhance diagnostic effectiveness for certain diseases, particularly those of the brain and spine. Certain contrast agents are also useful in diagnosing disease in bones and joints, liver, breast, and soft tissue. Contrast MRI is also useful in clarifying diagnoses and ruling out certain conditions. The use of contrast agents does not necessarily indicate that an abnormality has been identified.

The decision to use contrast agents is made by the referring physician. Consultation with the radiologist is recommended, particularly if a decision as to the clinical necessity is in question. Patients are routinely screened for any medical history that may rule out the use of contrast MRI, such as allergy, asthma, anaphylaxis or hemolytic anemia.

Blood tests to check kidney function are not generally required, as the contrast agents do not cause kidney disease.
