MRI DyeIf you have had a MRI and a contrast agent was used to enhance the image, you need to read the following. There are two very different and distinct kinds of dyes used and several brands of each dye. If you were given an Iodine-based dye then the following does not apply to you. However, if you were given a gadolinium-based contrast dye then you need to be aware of a serious skin disease that you have an increased risk to.

Gadolinium contrast agents have been linked to Nephrogenic Systemic Fibrosis (NSF) and Nephrogenic Fibrosing Dermopathy (NFD). Symptoms of these skin diseases include skin rashes, joint pain, stiffness, kidney failure, and renal failure. Gadolinium contrast agents are marketed under the names: Magnevist (gadopentetate dimeglumine), Ominiscan (gadodiamide), OptiMARK (gadoversetamide), MultiHance (gadobenate dimeglumine) and Prohance (gadoteridol).

Problems with Gadolinium MRI Dye

The potential problem with gadolinium dye result from recent statistical findings discovered in Denmark. On May 29, 2006, the Danish Medicines Agency reported that it had learned of 25 cases where patients who had been administered a gadolinium-containing contrast agent during the previous three months had contracted Nephrogenic Systemic Fibrosis (NSF), a very serious skin disorder. NSF, sometimes called Nephrogenic Fibrosing Dermopathy (NFD), is an incurable skin condition that affects patients suffering from kidney failure.

MRI Dye Side Effects

Symptoms associated with gadolinium dye exposure include:

  • Itching or burning skin
  • Reddened or dark patches on the skin
  • Skin rashes, hives or lesions
  • Tightening and swelling of the skin, usually in the extremities
  • Hardening or thickening of the skin
  • Restrictive movement
  • Skin texture changes (leathery, woody, scaly, like an orange peel)
  • Yellow spots on the whites of the eyes
  • Sharp pains in affected areas
  • Joint pain or stiffness
  • Deep bone pain in the hips or ribs
  • Calcification of muscle, skin, or tendons
  • Muscle weakness
  • Muscle contractures

Speak to a Lawyer

If you or a loved one had a MRI or MRA, and a gadolinium-based contrast dye, medium or agent was used to enhance the MRI image, then your health may be at risk. If you developed Nephrogenic Systemic Fibrosis (NSF), Nephrogenic Fibrosing Dermopathy (NFD), skin problems, skin tightening, severe joint problems, kidney failure, or renal failure, then you may be eligible to collect money damages for your injuries.

Please keep in mind that certain states limit the amount of time you have to file a lawsuit; contact an attorney as soon as possible.

The U.S. Food and Drug Administration (FDA) has asked manufacturers to include a new boxed warning on the product labeling of all gadolinium-based contrast agents which are used to enhance the quality of magnetic resonance imaging (MRI).

The requested warning would state that patients with severe kidney insufficiency who receive gadolinium-based agents are at risk for developing a debilitating, and a potentially fatal disease known as nephrogenic systemic fibrosis (NSF). In addition, it would state that patients just before or just after liver transplantation, or those with chronic liver disease, are also at risk for developing NSF if they are experiencing kidney insufficiency of any severity.

“FDA has been carefully monitoring potential safety signals related to these contrast agents after receiving reports about the risk of this potentially life-threatening disease,” said Steven Galson, M.D., M.P.H., director of FDA’s Center for Drug Evaluation and Research. “This latest action demonstrates FDA’s continuing vigilance about ensuring the safety of drug products once they enter the marketplace.”

Patients with NSF develop thickening of the skin and connective tissues that inhibits their ability to move and may result in broken bones. Other organs are at risk of thickening as well. The cause of NSF is not known and there is no consistently effective treatment of this condition.

FDA first notified health care professionals and the public about the gadolinium-related risks for NSF in June 2006 . Information on the risks was updated in December.

Gadolinium-based contrast agents are commonly used to improve the visibility of internal structures when patients undergo an MRI. Five gadolinium-based contrast agents have been approved for use in the United States: Magnevist (gadopentetate dimeglumine), Ominiscan (gadodiamide); OptiMARK (gadoversetamide); MultiHance;(gadobenate dimeglumine);and Prohance (gadoteridol).

Reports have identified the development of NSF following single and multiple administrations of the gadolinium-based contrast agents. The reports have not always identified a specific agent. Omniscan was the most commonly reported agent, when a specific agent was identified, followed by Magnevist and OptiMARK.

NSF also has developed after the sequential administration of Omniscan and MultiHance and Omniscan and ProHance. Because reports incompletely describe exposure to gadolinium-based contrast agents, it is not possible to know if the extent of risks for developing NSF is the same for all agents.

Patients should be screened for kidney problems prior to receiving one of these imaging agents. The recommended dose should not be exceeded and enough time should elapse to ensure that a dose has been eliminated from the body before the agent is used again.

There have been no reports of NSF among patients with normal kidney function or those with mild-to-moderate kidney insufficiency.
