Acute adverse reactions are encountered with a lower frequency than is observed after administration of iodinated contrast media. Gadolinium chelates are extremely well tolerated by the vast majority of patients in whom they are injected.

Although these agents can be differentiated on the basis of stability, viscosity, and osmolality, they cannot be differentiated on the basis of efficacy. Gadolinium chelates have been approved for parenteral use since the late 1980s. With the help of an intercommunication system, the patient can speak with the MRI technologist or radiology nurse specialist, squeeze the communication ball, and also get commands.Adverse Reactions to Gadolinium-Based Contrast Media* During the MRI procedure, the personnel on hand must monitor the patient.

These noises could be attenuated by the patient using headphones and earplugs during the scan. MRI scanner makes loud knocking noise during the procedure, which can cause damage to the hearing system. MRI departments should provide appropriate medications and facilities to deal with possible reactions to contrast in patients. It is also recommended that the patient be informed about the details and the time of the procedure before the scan.Īlthough gadolinium chelates are generally well tolerated, MRI technologists and physicians need to be aware of adverse reactions to these contrast agents. It is recommended that patients wear gowns in the MRI environment, To avoid metallic components of clothing. Discussion with a radiologist or referring physician might be helpful to determine whether an MRI scan is the most suitable imaging modality or not. If a patient has devices or implants, the make and model of the object requires a check against relevant databases and MRI safety websites. Patients need to be asked about any foreign substance that might interfere or with MRI acquisition. This screening is done during a verbal interview with the patient to ensure there is no contraindication for MRI. Nursing, Allied Health, and Interprofessional Team Interventionsĭue to potentially serious problems regarding safety issues with MRI, each patient needs to answer an MRI safety screening form before the scan. Thus, there should be no concern about continuing breastfeeding after MRI. Also, of that tiny amount excreted into the milk, only 0.8% is absorbed by the baby.

The gadolinium contrast is excreted into breast milk in less than 0.04% of the dose injected to a mother. MRI only be taken during pregnancy to rule out suspected abnormalities and on a 1.5-tesla scanner. Before MRI, a pregnant patient or who is suspected to be pregnant, the radiology team and physician should be informed. However, the FDA determines gadolinium as a class C agent, and there is no established definitive evidence regarding MRI safety during pregnancy. To date, there is no known adverse effect or specific consequence for fetuses exposed to non-contrast MRI. Patients who are pregnant: The administration of contrast during pregnancy is predicated on a risk-benefit assessment.ĭuring pregnancy, MRI is a helpful imaging technique to evaluate obstetric and nonobstetric disorders during any trimester.
