What is an MRI scan?

MRI stands for Magnetic Resonance Imaging. An MRI scan uses a very strong magnet, radio waves and a computer to produce pictures of the insides of your body. MRI scans are done by a Radiographer or an Assistant Radiographer Practitioner who are experts in getting high quality pictures and taking care of you throughout the scan. They may be assisted by a clinical imaging support worker

Why do I need an MRI scan?

MRI is used to diagnose many conditions, to plan treatment and monitor progress. It can give detailed information about any part of the body.

How do I prepare for the scan?

Please take your medication as normal unless you have been told not to. Your appointment letter will tell you if you should not eat and drink as normal before the scan.

Please do not wear eye makeup if we are scanning your head. Leave as much jewellery as you can at home and if possible, wear clothes without metal on them. You may still have to change into a gown. If you use a transdermal patch for medication, or a blood sugar monitor such as the Libre 2 freestyle you will have to remove it for the MRI scan. Please bring a spare one with you.

You may bring an adult friend or family member through to the scan room if you need their support, but only if they are safe to come in. They will need to fill out a safety form in the MRI department.

Please allow plenty of time for your visit. Aim to arrive at least 15 minutes before your appointment so there is time to prepare. Scan times can vary from fifteen minutes to an hour and a half, and you may need to stay a while afterwards.

What will happen?

Before your scan, an MRI team member will explain the procedure, check your details and go through your safety form. They will be happy to answer any questions. You will be asked to remove all metal objects apart from wedding rings. Many examinations will require you to get changed and gowns are provided.

You will lie down on a movable bed that will bring you to rest with the part of your body we are picturing at the middle of the scanner. The scanner is open at both ends all of the time. It is well lit and air-conditioned.

The scanners are very noisy when they are scanning but they do not hurt. You will be given ear protection for the noise.

During the scan, the radiographer will be observing you at all times through a window. They will talk to you over an intercom in between sections of the scan. You will also have a buzzer to press if you need assistance.

Like a photograph, MRI pictures can be blurred by movement, so it is very important to stay still.

Are there any risks?

MRI is considered one of the safest ways of imaging the body because there is no harmful radiation. A few people have a type of metal object in their body that could harm them in a strong magnetic field. There is a safety form with this letter. Please take time to fill it out now. Most metal in the body is safe for your MRI scan but we will need details to make sure. If you do not tell us about an implant in advance, you may not be able to have your scan for some days, until checks have been carried out.

Will I need an injection?

We take many different types of MRI pictures and for some we need to give you an injection of a clear fluid called a contrast agent. This is to make some parts of your body stand out better in the pictures.

The injection is given in the arm or back of the hand by a qualified member of staff. Please see the MRI Contrast information sheet for more information.

An injection to prevent your digestion from blurring your pictures may be given for some scans of the abdomen or pelvis. Please see the Buscopan information sheet.

What happens afterwards?

You can leave the department straight after the scan is finished unless you are told otherwise. If you have had an injection, you will need to stay in the department for 30 minutes after the injection. You may eat and drink as normal. Having an MRI scan will not prevent you from driving home.

Your results will go to the health care professional who sent you for the scan. We never give out results on the day.
