Are contrast dyes used within MRI's protected? I hold have two MRI's done short and one done beside a dye.?

Are contrast dyes used within MRI's protected? I hold have two MRI's done short and one done beside a dye.?
The same one - gadolinium edetate - has be used for several decades, so it should be pretty safe, otherwise it would own been replaced by presently.
if you're still alive.its safe!!
The contrast used within the MRI is safe if your kidney's are
functioning usually. "Gadolinium-based contrast agents increase the risk for nephrogenic systemic fibrosis (NSF) in patients near:
Acute or chronic severe renal insufficiency (glomerular filtration rate < 30mL/min/1.73m2), or
Acute renal insufficiency of any severity due to the hepato-renal syndrome or in the perioperative liver transplantation interval.
In these patients, avoid use of gadolinium-based contrast agents unless the diagnostic information is essential and not available with non-contrast enhanced captivating resonance imaging (MRI). NSF may result in mortal or debilitating systemic fibrosis affecting the skin, muscle and internal organs. Screen adjectives patients for renal dysfunction by obtaining a history and/or laboratory test. When administering a gadolinium-based contrast agent, do not exceed the recommended dose and allow a sufficient period of time for expulsion of the agent from the body prior to any readministration." This is a direct copy from the bracco web site, one of the contrast maker. This has primarily happen in nation with poor kidney function who have several MRI's in a jiffy period. At the hospital that I work at we immediately ask the patient if the own any renal issues and/or check their lab values if avaible.
Generally the MRI contrast is better tolerated than the x-ray contrast. It has a lesser amount of side effects and doesn't cause more trauma to the kidneys. Many fewer society are allergic, also.
