Depending on the MRI exam requested, you may be asked to change into a gown and robe. Jewelry, watches, hair clips, piercings and possibly dentures will need to be removed. You will have to leave all items containing metal, valuables and cards with magnetic strips (such as credit cards) in a locker outside of the MRI room.
A highly-skilled imaging technologist will operate the MRI scanner and tell you what to expect. An intravenous (IV) line may be placed in your arm so that contrast material can be injected. Images will be taken before and after the contrast material is injected.
You will be asked to lie on a cushioned, moveable table and may be positioned comfortably with bolsters. The technologist will provide you with headphones to listen to music. Earplugs are also available to muffle the noise. For the best quality images, you need to be as still as possible during the exam. You will hear a drumming sound as the machine captures the images. MRI exams often include multiple phases or sequences, some of which sound different and vary in length of time. You may be asked to hold your breath for approximately 20 seconds while the images are acquired.
The technologist is immediately available at all times, and can be summoned by using a call button, which will be placed in your hand. You will be in full view of the technologist by means of a window and video camera during the exam. Most exams take between 15-20 minutes to complete. A parent may be in the room during a child's exam.
