Getting ready for an MRI

Metal Implants

MRI is sensitive to any metal you may have in the body.  Inform the MRI technologist if you had surgeries or procedures involving the use of metal rods, plates, screws, braces or clips, and dental hardware (i.e. braces, retainers). If you have an implant, please give the MRI team information about the type of device and the manufacturer. If you have sustained an injury by a metallic object or foreign object (i.e. BB gun, bullet, shrapnel), or have body piercings and tattoos, please inform the MRI technologist. In some cases, you may need an X-ray to confirm it is safe to complete an MRI scan.


When a patient is very young or has a history of claustrophobia, or a fear of small spaces, a mild sleeping aid might be given to make sure the patient lies still during the procedure.

Needle during an MRI scan

To get more important information from MRI pictures, a special liquid or contrast medium called gadolinium may be given to a patient.  This liquid is put into the vein in the hand or arm using an intravenous line (IV). The IV is put in with a small needle. If needed, the IV will be inserted before the MRI scan. Contrast medium is normally very safe, but it may produce a reaction in rare cases. The MRI technologist will watch the patient very closely during and after the MRI to see if the patient has a reaction. The team is trained to deal with these problems if they happen. A member of the team will discuss the risks with you before the MRI.
