Because the MRI machine uses a large magnet, metallic objects and mechanical devices are not allowed into the examination room. Metallic objects will fly across the room and mechanical devices will malfunction in the MRI room. It is therefore requested that you not wear any jewelry or watches to the examination since they will have to be removed. Comfortable clothing with as little as possible metal accessories is advised. Mascara is to be avoided since it may contain a metallic base. Hair pins or clips must be removed prior to the examination. It is best to remove dental devices prior to the procedure.
You will be asked several questions prior to the MRI procedure in order to assure that there is no contraindication to performing the test. The following special considerations apply:
You will be asked if you have ever undergone a surgical procedure. Metallic clips, screws, stents, artificial valves or implants may prohibit you from having the MRI procedure. Most, though not all, devices are now MRI compatible.
If you have a pacemaker, an implanted pump or a stimulation device such as a Deep Brain Stimulator (DBS) or Spinal Cord Stimulator you will not be able to undergo this procedure.
If you have any metallic fragments in your eyes you will not be able to undergo this procedure. If you have fragments of explosive devices or bullets in your body you will not be able to undergo this procedure.
There are no dietary restrictions. However, it is advisable not to consume a full meal prior to the examination as this might make you feel uncomfortable during the procedure. Avoid stimulants such as caffeine containing beverages. Although not required, try to sleep during the procedure if at all possible.
Objects with magnetic strips such as credit cards may be damaged and are best kept at home or at least removed prior to the procedure.
