About the MRI
MAGNETIC RESONANCE IMAGING (MRI)?
MRI is an exam which uses a computer, magnetic fields and radio waves to generate images of the internal structures within the body. MRI does not use any form of ionizing radiation.
WARNING: Do not enter the MRI room if you have metallic, electronic, magnetic, or mechanical implants/devices which may be hazardous to you. Consult the MRI Technologist BEFORE entering the MRI room. The MRI magnet has a very strong magnetic field and is ALWAYS on!
CHECK WITH YOUR PHYSICIAN IF:
- You are pregnant or think you may be pregnant
- You have any surgically implanted hardware (Please bring your implant ID card)
- You have or had an eye injury involving any metallic fragment(s) or foreign object(s)
- You have worked as a welder or grinder of metal
- You have retainers/braces- PROHIBITED FOR SOME EXAMS
- You have an Aneurysm Clip(s)- STRICTLY PROHIBITED
- You have a Cardiac Pacemaker- STRICTLY PROHIBITED
WHAT WILL THE EXAM BE LIKE?
Before your exam, the MRI Technologist will obtain a detailed medical history, explain the procedure, and answer any questions you may have. The MRI Technologist will walk you into the MRI room, position you on the padded table, provide a panic bulb, and smoothly transition you into the magnet opening. Your physician’s order will determine how far you are transitioned into the magnet opening. The exam itself is painless – in fact, you won’t feel anything. You will hear a knocking sound which means your images are being taken. During this time, it is very important that you remain calm to avoid prolonging your exam. Should you require immediate assistance during the exam, squeeze the panic bulb. Special headphones and your choice of music are provided during most MRI exams.
NOTE: You will be required to wear earplugs or headphones during the exam to prevent possible problems or hazards related to acoustic noise.
Some exams require an intravenous (IV) contrast injection of dye. The contrast dye has a very low risk of side effects and is used to better visualize the internal structures being studied. If your MRI exam requires a contrast injection, a representative will call you in advance to provide further instructions.
HOW LONG DOES THE EXAM TAKE?
Most exams require 30-45 minutes; however, this is dependent on patient cooperation and the type of study ordered by your physician.
PREPARATION FOR THE MRI EXAM:
On the day of your exam:
- Take pain medication one hour before your exam
- Do not wear any make-up & keep hair dry
