Magnetic Resonance Imaging (MRI)
Magnetic Resonance Imaging (MRI) is a type of scan that uses strong magnetic fields and radio waves to produce detailed images of the inside of the body without the use of radiation. The MRI scanner is a tube which is open at both ends. The MRI scanner is operated by a Radiographer, who is trained in performing imaging investigations.
You will complete a detailed MRI safety checklist prior to entering the MRI scanner to ensure that all metal objects are removed and any previous surgeries involving metal are fully documented and you are able to proceed with the examination.
The Radiographer can see you at all times and talk to you through an intercom. The MRI scanner is very noisy.
MRI scans are used to help diagnose conditions, plan treatments and to see how effective previous treatment has been.
There are currently five MRI scanners located at the RDUH (Eastern) Wonford site. Two 1.5T MRI scanners are located in the main hospital building within Medical Imaging and two 1.5T mobile MRI scanners located in the Child and Women’s Health Car park that are operated by a private provider. There is a 3T MRI scanner, in partnership with the University of Exeter, to scan research and clinical patients in the Mireille Gillings Neuro Imaging Centre (MGNC). We have a 1.5T scanner at the Exeter Nightingale Community Diagnostic Centre (CDC).

More about us
MRI stands for Magnetic Resonance Imaging. The MRI scanner is a large cylinder-shaped tube which is open at both ends. Images are produced by using a large magnet and radio waves. A computer then processes the signals and generates a series of images of the scanned area.
You should not feel any discomfort during an MRI scan. It is a non-invasive procedure and does not use X-rays.
The strong magnets used during the scan can potentially affect any metal implants or fragments in your body. Before your appointment, please contact us to let us know if you have any implanted devices. Some implants are contraindicated for MRI or we may need to make a special arrangement. If you have a pacemaker, any cardiac implant or repair, a gastric band, a cerebral aneurysm clip, inner ear implant, diabetic monitor, muscular and neuro-stimulator or any other electronic device or vascular stent please let us know.
If you have a history of metallic fragments in your eye, please contact us for further instructions prior to your scan.
On arrival, all patients have to complete a MRI safety checklist to ensure that it is safe to go ahead with the scan.
For some procedures, the patient will be asked to change into a gown. Please avoid bringing valuables. If you have to, they can be locked away until after the examination.
When all the checks are complete, the radiographer will take you into the MRI scanning room and you will be asked to lie down on the MRI table.
The radiographer will then move the table into the scanner. The area that we have been asked to look at will be in the centre of the machine. It is important to lie very still for the scan so that the pictures are not blurred.
The machine is very noisy so earplugs and/or ear defenders are provided. Music can be played from either a CD or the radio. You will be given an alarm to hold which can be activated should you wish to attract the attention of the radiographer, who can talk to you via a two-way intercom.
MRI examinations consist of a series of sequences, each of which can last for several minutes. An MRI scan can take from 10 minutes to up to one hour to complete.
The patient is usually alone in the scanning room. Some patients might find that they are claustrophobic and are unable to complete the examination. The radiographers will do everything that they can to put you at ease. If we are unable to complete the procedure, it might be possible for the scan to be re-booked with sedation.
For some examinations, an injection of Gadolinium (contrast dye) might be given. For some abdominal or gynaecological procedures, it might be necessary to use a drug called Buscopan. Before giving you an injection, the radiographers will ask you some additional questions to make sure it is safe to do so.
If your scan is booked with a contrast injection and you are pregnant or breast feeding, please contact us before attending the appointment.
If you have any mobility issues, please inform the MRI booking team so that we can ensure this is taken into account when selecting the best scanner for your appointment.

Children and young people
Our team is very experienced at scanning children and young people. A parent can stay in the room, as long as they have been successfully screened for safety.
Very young babies can usually tolerate the scan after a feed.
Other children might require a general anaesthetic. There are three or four of these sessions per month.
If you have any questions, please contact your referring doctor or us.
A video on what to expect when coming into hospital for an MRI scan is available for children to watch.
