The magnetic resonance imaging (MRI) chamber is a relatively tight space, and individuals undergoing a scan are required to lie still for up to one hour, sometimes as long as two hours.

Some people may feel uncomfortable or claustrophobic in this environment. Sometimes radios are available to help patients relax, but those who become very anxious in small spaces may want to discuss with their physician the possibility of receiving a mild sedative during 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, so the images are not as clear.

The patient is placed on a long bed that slides into the MRI chamber. The individual 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. The MRI equipment will make many types of noises during the scan as it takes multiple views of the target site. These noises are a normal part of the MRI procedure. A nurse or technician will periodically make sure that the patient is comfortable and able to continue.

Those taking the test should be able to leave immediately following the MRI with no side effects. However, if a sedative is administered, patients will be monitored until the effects of the sedative have passed. They will then need a friend or relative to drive them home.

Results of the test are recorded on film. After receiving the radiology report, the physician will be more prepared to confirm a diagnosis or prescribe further tests and treatments.
