The magnetic resonance imaging (MRI) chamber is a relatively tight space, and individuals undergoing a scan may be required to lie still for an hour or more, sometimes as long as two hours. Some people may feel uncomfortable or claustrophobic in this environment. In many machines, music can be played via speakers or headphones to help patients relax. Individuals who become anxious in small spaces may want to discuss with their physician the use of a sedative prior to the procedure. Newer “open” MRI scanners have been designed to increase patients’ comfort levels, but they are subject to more background interference in the images they produce.

The patient is placed on a long bed that slides into the MRI chamber. The technician usually administers the MRI from a control room or small area separate from the scanner. However, the technician and the patient are able to communicate during the test through an intercom system. This allows the technician to provide instructions and the patient to express any concerns. Some patients may be given a hand-held buzzer to stop the test in case of some type of emergency.

Once inside the chamber, the patient should relax and lie still for the duration of the procedure. Patients may be instructed to hold their breath at times or may be removed from the scanner for repositioning.

The MRI equipment will make many different types of noises during the scan. These may include loud thumping or buzzing sounds as the machine takes multiple views of the targeted site. These noises are a normal part of the MRI procedure. A nurse or technician periodically checks with the patient during the scan.

Those taking the test should be able to leave immediately following the MRI with no side effects. Patients who have received a sedative may need someone to drive them home after the test.

Results of the test are recorded on a series of films. The films are reviewed by a radiologist and a complete report will be written by the examining radiologist. A copy of the report is sent to the patient’s physician to help confirm a diagnosis or prescribe further tests and treatments.

Some physicians may request that patients bring their MRI films with them to a follow-up appointment. Individuals should check with the facility to determine the correct procedure for obtaining their films prior to their appointment.
