A magnetic resonance imaging (MRI) scan does not expose patients to radiation and has no known harmful effects. The MRI machine uses a large magnet and a computer to take pictures of the inside of your body. Each image or “slice” shows a few layers of body tissue at a time. A radiologist on a computer monitor then examines those pictures. Each MRI test can take between 25 to 60 minutes.
The MRI machine is a large, cylinder-shaped tube surrounded by a circular magnet. You may be asked to change into a hospital gown for your MRI procedure. Your technologist will help you lie on an examination table that will slide into the center of the magnet. You will be asked to hold very still, and the body part to be tested may be kept in place with a cradle or straps. If you move, the MRI pictures may be unclear. Your technologist will sit behind a window during your examination and will be able to see, hear and speak to you at all times.
You will hear very loud banging sounds during the series of scans – this noise is caused by the magnets moving and is totally normal. Before your procedure, your technologist will offer you earphones (to listen to music) or earplugs. We encourage you to bring your own playlist, or you can choose from our music collection.
Sometimes, MRI examinations require intravenous contrast material. This assists the radiologist in getting a better view of the affected body part. The contrast material is put through an intravenous (IV) line in a vein in your hand or arm. For your safety, contrast screening may require blood work prior to your scan. This is performed right here at the Imaging Center. Please note, before your MRI procedure, your technologist may ask you a series of questions to ensure your safety.
Because the MRI machine uses a strong magnet, certain types of metal within your body could be pulled toward the magnet. You will be asked to remove all jewelry, piercings, and other metal objects. Any clothing with metal hooks, buttons, zippers, or the like, must also be removed. Your safety is our primary focus.
Please note, for your safety, if you are pregnant or could be pregnant, you will need to inform your technologist prior to your imaging procedure.
