What will I experience during and after the procedure?
Most MRI exams are painless. However, some patients find it uncomfortable to remain still during MR
imaging. Others experience a sense of being closed-in (claustrophobia). Therefore, sedation can be
arranged for those patients who anticipate anxiety, but fewer than one in 20 require medication.
It is normal for the area of your body being imaged to feel slightly warm, but if it bothers you, notify the
radiologist or technologist. It is important that you remain perfectly still while the images are being
recorded, which is typically only a few seconds to a few minutes at a time. For some types of exams, you
may be asked to hold your breath. You will know when images are being recorded because you will hear
tapping or thumping sounds when the coils that generate the radiofrequency pulses are activated. You
will be able to relax between imaging sequences, but will be asked to maintain your position as much as
possible.
You will usually be alone in the exam room during the MRI procedure. However, the technologist will be
able to see, hear and speak with you at all times using a two-way intercom. Many MRI centers allow a
friend or parent to stay in the room as long as they are also screened for safety in the magnetic
environment.
You may be offered or you may request earplugs to reduce the noise of the MRI scanner, which produces
loud thumping and humming noises during imaging. MRI scanners are air-conditioned and well-lit. Some
scanners have music to help you pass the time.
When the contrast material is injected, it is normal to feel coolness and a flushing sensation for a minute
or two. The intravenous needle may cause you some discomfort when it is inserted and once it is
removed, you may experience some bruising. There is also a very small chance of irritation of your skin
at the site of the IV tube insertion.
If you have not been sedated, no recovery period is necessary. You may resume your usual activities and
normal diet immediately after the exam. A few patients experience side effects from the contrast material,
including nausea and local pain. Very rarely, patients are allergic to the contrast material and experience
hives, itchy eyes or other reactions. If you experience allergic symptoms, a radiologist or other physician
will be available for immediate assistance.
