Before your MRI exam begins, Eastside’s staff will position you onto a sliding table, which moves into the MRI system opening where the magnetic field is created. While MRI sequences are performed you will hear tapping or clicking sounds during the exam. This sound indicates the magnetic field gradient coils are being switched on / off to measure the MRI signal reflecting from your body. If you need to communicate with the MRI technologist at any time during the procedure there is an intercom for communication.
Your MRI exam should take somewhere between fifteen to forty-five minutes, depending on how many images are needed. Some detailed studies may take longer. MRI subjects will be asked to remain still while the imaging sequences take place. Each imaging sequence lasts for only a minute or two at a time.
Depending on the part of the body being examined, a contrast agent may be used to enhance the visibility of certain tissues or blood vessels. Eastside MRI’s technologist may use a small needle to inject the contrast agent into veins in the arm or hand.
