Can an MRI and MRA be performed without gadolinium-containing contrast?
MRI can be performed without contrast. However, gadolinium-containing contrast agents provide better diagnostic information in many instances as compared to MRI without contrast. The use of a gadolinium-containing contrast agent to enhance MRA is not FDA approved. MRA is able to provide detailed images of blood vessels without gadolinium-containing contrast. The use of gadolinium-containing contrast agents has been reported to enhance MRA. 4. Are there other approved MRI contrast agents that do not contain gadolinium? There are no other approved MRI contrast agents. Imaging contrast agents, such as iodinated contrast agents are used in Computed Tomography, plain X-ray and X-ray angiography. However, these iodinated contrast agents require X-ray imaging rather than MRI. 5. What is the concern regarding gadolinium-containing contrast agents? The information in the May 29, 2006, press release from the Danish Medicines Agency (DMA) and the January 2006 report by Grobner et al in Nephrology
