Gadolinium Deposition Disease Symptoms Typically Begin Couple Of Months After Use And Can Continue For Many Years Without Any Diagnosis (Posted by Tom Lamb at DrugInjuryWatch.com) During MRI and MRA procedures patients often receive injections of gadolinium-based contrast agents (GBCAs). Some of those contrast agents with gadolinium are classified as linear GBCAs -- as opposed to macrocyclic. Gadolinium is a heavy metal found deep in the earth. It is highly toxic in its free (uncovered) form. MRI and MRA contrast agents containing gadolinium are supposed to be secreted out of the body quickly, but some people, especially those with impaired kidney function, may not be able to secrete it as quickly as necessary The first gadolinium-based contrast agent was approved in the United States. Four agents were approved in the United States in the past decade and they have set a string trend in the industry to continue to find more efficient, more accurate, and safe agents. The contrast media sales are expected to increase in the United States in the coming. Gadolinium-based contrast agents (GBCAs) have been suggested as off-label alternatives to iodine-based contrast agents for fluoroscopic imaging during interventional pain procedures. We report a case of accidental intrathecal administration of a GBCA during a neuraxial interventional pain procedure leading to acute gadolinium neurotoxicity, which resulted in encephalopathy and ultimately death From the nonionic iodinated contrast agent with the highest concentration available and support from landmark safety studies, to the extracellular gadolinium-based contrast agent with the highest relaxivity and an FDA-approved indication for MR angiography, to the line of barium sulfate products for use in gastrointestinal radiology and CT, and for which we are the only supplier, to innovative.
