What is a MRI Scan?

MRI stands for Magnetic Resonance Imaging. MRI is a state-of-the art diagnostic tool which provides detailed and precise images of the body. MRI scans are able to produce images of organs, tissue and blood vessels.

As a patient, it is important for you to know MRI does not use X-Rays or radioactive materials. MRI generates scans (images) based on the interaction between the hydrogen atoms in your body, a large magnet and radio waves. Stimulated by ordinary radio waves within the powerful magnetic field of the large magnet, these atoms give off signals which are collected and fed into a computer. The computer then generates sets of scans out of these signals. A board certified radiologist view these images to make a diagnosis.

What are Some Common Uses for MRI Scan?

MRI is very sensitive in differentiating diseased and normal tissues and is not affected by the dense bony structures of the body. It is currently regarded as the ideal way to diagnose disorders of the brain, spine and joints, with valuable use in certain abdomen, pelvis, bone and cardiovascular problems. The test may help identify problems that are difficult or impossible to detect by other imaging methods, and can sometimes reveal abnormalities before they are visible with other tests.

What Preparation do I Need for my MRI Scan?

There are no special diet restrictions for the MRI exam. You may be asked to answer a few questions and sign a consent form. Some exams require an injection given through the vein in the arm, which does not contain iodine, nor is it radioactive. The small injection of MRI contrast agent (gadolinium) helps the doctor better visualize organs and other structures. This agent can also demonstrate how well your organs are functioning.

If you wear clothing with metal zippers, or snaps, you will be asked to change into a hospital gown. In addition, you will be asked to remove any jewelry, hair pins and other metallic objects before your exam.

For Your Safety

Due to the strong magnetic field which can affect the function and position of certain devices, individuals with an implanted pacemaker, defibrillator or brain aneurysm clips should not be scanned. All implants should be cleared by the MRI Center before your exam. Please inform the MRI Center of such objects, metal fragments or old war wounds. You may be required to have an X-Ray to exclude metal fragments in the region of the eyes or other areas.

What is a MRI Scan Like?

An MRI exam is painless. Although MRI is a very advanced medical technique, this exam will probably be one of the easiest and most comfortable exam you have ever had. A specially educated MRI technologist will ask you to lie down on a padded contoured bed in the room with the MRI scanner. You will be given either earplugs or a music head set to wear. Specialized receivers will be placed over the area of the body to be imaged. If it is the head that will be imaged, your head will be placed in a comfortable cradle. The table will slide you into the center of the magnetic field. You will hear some humming and thumping noises which are normal. These noises will last several minutes with pauses in between. Your test might last from 30 to 45 minutes. The technologist will be able to hear, see and speak to you during the exam.
