An MRI scan is performed by a Magnetic Resonance Technologist. The MRI Technologists will have you lie on a table that is connected to the MRI scanner. You will be properly positioned and the coil (cameras) will be aligned with the target body part. The MRI is quite noisy and therefore the Technologist will give you ear plugs. To hear what the MRI sounds like you can click here.
Your exam will be a compilation of multiple scans of the target area. Between scans, the technologist may talk to you and let you know how long each scan will be. Depending on what type of scan you are having, the technologist may give you instructions when to hold your breath and when to breathe.
In some circumstances a contrast agent called Gadolinium is used to make your tissues and blood vessels show up more clearly in a MRI image. Gadolinium is a clear, colorless fluid that is injected with a small needle into a vein in your arm or hand. It produces few side effects, though you may get a metallic taste in your mouth. Gadolinium is excreted by the kidneys through your urine usually within 24 hours. It is quite safe; however, as with all medications, there is a slight risk of an allergic reaction and will not be used when renal failure is present. The doctors and staff in the MRI department are trained to respond to any emergency situation that may develop.
Before an MRI exam, eat normally and continue to take your usual medications, unless otherwise instructed. You may be asked to change into a gown if your clothing has metal on it. You will be asked to remove jewelry, hairpins, eyeglasses, watches, wigs, dentures, hearing aids, and bras (unless it is a metal-free sports bra). If you are unsure about advance preparations for your exam, please call the MRI department and we will be happy to answer any questions. After the exam, a report will be sent to your doctor. Your doctor will then provide you with the information.
