For the majority of MRI examinations there are no special preparations required, some more specialist applications (such as bowel imaging) will require preparation.

Abdominal examinations may require fasting prior to the study which we would inform you about in advance.

What you must do and tell us in advance

• If you’ve ever had an injury involving embedded metal (for example in the eyes)
• If you’re coming for a brain scan, please do not wear eye make-up (it interferes with the scan)
• If you’re diabetic and / or have problems with kidney function

Contrast (MRI dye)

Some studies require the injection of Gadolinium MRI contrast dye to brighten the appearance of soft tissues, organs and blood vessels. This is injected via a small inserted intravenous (IV) cannula which we will insert before your examination and remove before you leave.

You will need to have had your kidney function checked before coming so that we can safely inject the contrast medium and ensure your body clears it away.

 Pregnancy

MRI scanning is usually avoided during the first trimester of pregnancy, although it has been shown not to be dangerous in this period in the scanning of in utero babies. No detrimental effects to pregnancy have ever been demonstrated with MRI scanning.

On arrival, you will meet the specialised MRI radiographer who will perform your investigation. A safety check will be performed and you may be asked to change into a gown.

All metallic objects will be removed from your person and you may need to have an x-ray of certain body parts to check for metal if there is a risk of embedded metallic fragments.

You will be laid on the MRI scanner table. A coil will be placed over the body part we are investigating and secured in place. The radiographer will apply padding and cushions to make you as comfortable as possible.

You will need to lie in place for up to one-hour (average 20-40 mins) whilst images are taken. During the taking of images you will be instructed to lie completely still for 3-7 minutes at a time and for some examinations you will be instructed to control your breathing.

If you are having intravenous contrast, the radiographer will come into the room and inject the contrast through your cannula and resume imaging.

 Noises during the scan

MRI scanners make unusual clicking, banging and grinding noises as they capture images. They have a reputation for being very noisy, but things have changed and our modern scanners are really not very loud.

We will provide you with either some headphones or earplugs during your investigation for your comfort.
