While the patient is lying on a flat narrow table, the table is moved along into a narrow tubelike structure. The procedure may take one hour to complete. While the images are taken, a drumming or banging noise may be heard. This is normal. This noise does not become louder during the test, although the human ear may interpret it as such.
Ear plugs are often available for use.
A technician is in another room operating a computer. An intercom and mirror are in use during the procedure so that the technician can see and hear the patient. Some patients find the machine to be somewhat claustrophobic. A mild sedative will help to better tolerate the procedure in such cases. Small children will require teaching and a sedative prior to having an MRI scan.
