During an MRI scan the patient will hear loud noises that are generated within the MRI unit while images are being produced. The patient can usually ask for earplugs to reduce the sound of the MRI scanner. Some of the newer scanners have music to help the patient pass the time. They also may be air-conditioned and have lights inside.(1)
Although most patients will spend between 30 and 60 minutes in the MRI machine, they are allowed to take breaks between sequences so that they are not required to lie still for the entire time.(2) Throughout the exam the patient will be able to talk to both the radiologist and the technologist, though they will both leave to observe from an adjacent room during the actual imaging process. Additionally, some facilities allow for a relative or close friend to stay near the patient during an exam.
MRI is normally a pain-free process that requires no recovery period afterwards. Occasionally patients have side effects from the contrast material such as nausea and local pain, and, very rarely, patients can have an allergic reaction to the agent that results in hives and itchy eyes. Nursing mothers should avoid breastfeeding for 36-48 hours after having an MRI scan using contrasting agent.(3) Those with kidney problems should avoid gadolinium-based contrast material. Most people who have an MRI scan are able to resume their normal activities and diet immediately after the exam.(2)
