Gadolinium based contrast agents
Gadolinium based contrast agents are paramagnetic ions that are often used in MRIs. These contrast agents move differently in magnetic fields than other agents. This provides contrast in the output of MRIs, making it easier for doctors to see tumors, lesions and other problems that need to be addressed.
This type of medication should only be administered if absolutely necessary. It’s possible to have an MRI without taking the medication, and this medication has certain risks.
- Patients with seizure disorders may have a seizure as the result of the medication.
- Patients with heart disease have an increased risk of heart attack or heart failure.
- Patients with kidney disease may not eliminate the medication from their bodies appropriately, which can cause further problems with the kidneys.
