The findings were recently published online in the journal\u00a0<i>Radiology<\/i>.<\/p>\n<p>In this study, Mayo Clinic identified patients who donated their body to medical research and had undergone multiple gadolinium contrast-enhanced MRI exams during their lifetime. Brain tissue samples from these patients were then compared to donors who had never received a gadolinium contrast agent. <strong>The patients exposed to the gadolinium contrast had measurable quantities of gadolinium deposited in their brain tissue, whereas those never exposed to gadolinium had none<\/strong>. Researchers were able to directly measure gadolinium concentrations and visualize patterns of deposition in brain tissues. &#8220;Given that these agents are administered millions of times every year, this is an important discovery,&#8221; says study author, Laurence Eckel, M.D., radiologist, Mayo Clinic.<\/p>\n<p>&#8220;Despite evidence that trace amounts of gadolinium are depositing in neural tissues, there is currently no data to suggest that it&#8217;s harmful to patients,&#8221; says Dr. Eckel. &#8220;<strong>These FDA-approved, gadolinium-based contrast agents provide critical information to radiologists and other physicians, enabling more accurate and timely diagnosis of disease<\/strong>. Such information is essential in guiding both medical and surgical decisions for best patient care,&#8221; he continues.<\/p>\n<p>The Mayo Clinic Department of Radiology continues to recommend the use of gadolinium-based contrast agents whenever they are clinically appropriate based upon all available data.<\/p>\n<p><strong>&#8220;The findings challenge our understanding of how these agents distribute in the body following intravenous gadolinium contrast administration<\/strong>. These agents have been safely used for years, benefiting patients around the world,&#8221; says Dr. Eckel. &#8220;We now simply have a few more questions that the medical and scientific communities will seek to answer. Efforts are underway to do just that.&#8221;<\/p>\n<p><strong>Key points for patients to consider:<\/strong><\/p><\/blockquote>\n<ol>\n<li>\n<blockquote><p>Tens of millions of patients have received gadolinium contrast without incurring any related health problems.<\/p><\/blockquote>\n<\/li>\n<li>\n<blockquote><p>Although research demonstrates deposition in brain tissues, no specific symptoms or diseases have been linked to this finding.<\/p><\/blockquote>\n<\/li>\n<li>\n<blockquote><p>If a patient has a medical condition requiring evaluation with MRI, the risk\/benefit ratio still strongly favors administration of gadolinium in those cases when it is indicated.<\/p><\/blockquote>\n<\/li>\n<li>\n<blockquote><p>There is no known disease associated with gadolinium deposition in the brain. To date, the only known disease related to gadolinium injections is nephrogenic systemic fibrosis, a condition only occurring in a tiny subgroup of patients with renal failure.<\/p><\/blockquote>\n<\/li>\n<li>\n<blockquote><p>A patient or parent, as always, maintains autonomy to decline gadolinium administration; however, the quality and usefulness of the exam may be reduced.&nbsp;<\/p><\/blockquote>\n<\/li>\n<\/ol>\n<p>About Mayo Clinic<\/p>\n<p>Mayo Clinic is a nonprofit organization committed to medical research and education, and providing expert, whole-person care to everyone who needs healing.
