    You will typically receive a gown to wear during your MRI examination.

    Before entering the MRI system room, you will be asked questions regarding the presence of implants (for example Cardiac pacemakers/defibrillators, internal metal clips or implants, metallic foreign bodies, cardiac stents etc) and will be instructed to remove all metal objects from your pockets, wrists,hair & body piercings.

    Items that need to be removed by patients and individuals before entering the MRI system room include:

    You will be placed on an examination bed & moved into a tunnel. The procedure is often fairly lengthy.

    During the acquistion of images the machine will make a loud noise. You will be offered earplugs to minimise the noise you experience.

    You will be able to communicate with the MRI technologist or radiologist at any times using an intercom system or by other means.
