Frequently Asked Questions

Are there other approved MRI contrast agents that do not contain gadolinium?

Gadolinium | Frequently asked Questions | Pharmaceutical Lit...
Yes. However, the two other approved MRI contrast agents, Feridex, I.V. (an iron-containing injectable solution) and Teslascan (a manganese-containing injectable solution) are FDA-approved only for the evaluation of lesions of the liver. 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.

This is only done when the radiologist and/or the referring physician have determined that it is necessary for diagnostic purposes. Gadolinium contrast is used to make specific organs, blood vessels or tissue types "stand out" with more image contrast in the resulting picture.

What is an MRI?

Frequently Asked Questions -- Advanced Centers for Orthopaed...
The magnetic resonance imaging (MRI) machine uses magnetic rays rather than x-ray to show the soft tissues of the body. With this diagnostic tool, radiologists are able to slice through the area of interest to the surgeon. Usually this test is done to look for injuries such as tears in the meniscus or ligaments of the knee. The test does not require any needles or special dye and is painless.

Who cannot have an MRI?

FAQ's
If you have a pacemaker, you should not be imaged because the pacemaker may be damaged in the magnetic field of the scanner. If you have metal filings, shrapnel, or ferromagnetic clips or pins in your body, you probably will not be imaged because these objects could be twisted by the magnetic field and cause serious injuries. Most new surgical metal implants are made of a high quality stainless steel which is non-magnetic. You can be imaged with these. Dental fillings and bridgework are okay.

Why is the gadolinium necessary?

Breast cancers have a rich blood supply, so tumors "light up" on MRI, helping to distinguish them from normal breast tissue. These are called areas of "enhancement." It is the contrast agent (gadolinium) that makes breast MRI so much more sensitive in cancer detection than mammography.
