Hi. The usual contrast agents used for brain MRI's are also gadolinium containing compounds which are not very different from the ones used for liver MRI's. The mode and dose of administration would probably differ. Again I have not encountered reports in scientific literature regarding contrast agents causing severe pain. My guess is your child's pain may have some other cause. Have you informed her doctors about this? What have the doctors done to investigate the cause of the pain? Is she receiving adequate pain medication?
Thanks for the information I really appreciate it . But I curious to know if the MRI contrast's for the brain are the same contrasts they use for other parts of the body. If they are do they use different doses for different scans . The reason I am asking is because she just had a scan of her brain again this past Tuesday and as of today she is still in severe pain
Hi. I have searched the literature regarding the adverse effects of the usual contrast agents (gadolinium chelates and ferumoxides) used in MRI imaging of the liver and gallbladder. These are not toxic to the liver, nor are they known to induce the formation of gallbladder stones. Your child's pain and gallbladder stones are most probably unrelated to the use of the MRI contrast agents. If you want more information, there's a good article providing an overview of these drugs . I have to warn you though, that the article may be a little bit too technical for non-medical people. But if you're curious, you may wish to look it up (http://radiographics.rsnajnls.org/cgi/content/full/26/6/1621).
