Having your scan

This information tells you about having an MRI scan with us (following referral by your doctor) and aims to answer any questions you might have.

Please read this information carefully, and if you have any questions or concerns then contact us on 01923 886311 between the hours of 9am and 5pm, Monday to Friday.


What is an MRI scan?

MRI (magnetic resonance imaging) is a scanning technique which uses magnetic fields and radio waves to create images of tissues, organs and other structures inside your body. It is painless.

The images may be useful in diagnosing illness or in helping your doctor plan appropriate treatment for you. The MRI scanner is a long open-ended tube surrounded by a large circular magnet, and the couch is about 1.8 metres or six feet long — see picture. You will need to be able to lie on your back on the scanning couch, which will move into the tube.

What are the risks of having an MRI scan?

MRI scans don’t use X-rays and there are no known risks or side effects associated with them.

MRI scans are not suitable for everyone due to the magnetic field. Our team will complete an MRI safety checklist with you before you have your scan to ensure
that you meet the necessary safety criteria

Preparing for your scan

Your appointment letter tells you how to prepare for your scan. Please read it carefully and follow the instructions.

Having an MRI scan is painless. However if you do need something to calm your nerves or reduce pain, please speak to your doctor in advance and follow their advice closely. If you’ve taken a sedative, you must bring someone with you to your appointment. Please remember our staff are unable to give sedatives or painkillers.

On the day

Please take your prescribed medicines as usual.

Your appointment letter tells you which of the following options apply to you:

Option 1: Eat and drink as normal.
Option 2: Avoid eating for two hours before your scan.
Option 3: Do not eat or drink for six hours before your scan.
Option 4: Do not eat or drink for six hours before your scan. For this test you will need to drink some fluid known as contrast medium 1 hour prior to the scan. This will be a white liquid containing barium. It is used to highlight your stomach and bowel on the scan images.

If the above instructions affect the way you take your medication, please ask your pharmacist or doctor for advice.
If you are diabetic, please ring us for advice if you are worried about any of these instructions.
Please bring a dressing gown or wear metal-free clothing, and bring your favourite music on CD, MP3 player, iPod® or your mobile phone.

  • Due to Coronavirus (Covid-19) we are discouraging our patients from bringing friends and family along to appointments. One person will be permitted to accompany a patient if they require support with translation, physical disability, a mental health issue, learning disability, autism or dementia. Please don’t bring children with you.

Avoid bringing valuables along to your appointment, as we only have limited secure space to store them for you.

If you’re unable to attend, please phone us as soon as possible.

The centre opens at 7.30am. If you have any urgent questions before 9am, or if you’ve got a weekend appointment and need to
speak to us on the day of your scan, please phone 01923 886310 and dial extension 375 for reception.

You are asked to report to the Paul Strickland Scanner Centre reception area 15 minutes before your appointment time. This is so there is time for you to get changed and complete your safety questionnaire. We try to scan patients on time, although delays can

Having your MRI scan

  • You will be asked to remove all metal objects from your person, including any piercings. A locker is available for personal items.
  • Depending on what you're wearing you may be asked to changeinto a hospital gown. You can bring your own dressing gown instead.
  • Do not wear any sports clothing with antibacterial properties - it contains metal and could therefore cause injury during scans.
  • A member of staff will go through a safety checklist with you.
  • You will then be taken into the scanner room and asked to lie on the scanning couch. Depending on the body part we are scanning you may go in head or feet first. We will put a receiver called a “coil” on the body part of you that we are scanning. This detects the signals emitted from your body. Once you are comfortable, all you need to do is relax and remain very still.
  • The scanner room can be quite cold but you will be offered
    blankets to keep warm. You may warm up during your scan - this
    is a normal side-effect of having an MRI scan.
  • We will give you ear protection because the scanner makes loud rhythmic knocking and buzzing noises. The noises will change during the scan. Your music will be played through the headphones. We will give you a buzzer which you can use to contact the radiographer at any time.
  • The radiographer can see you during the scan. You can talk to each other through the two-way intercom.
  • During scanning we may ask you to hold your breath several times for short periods. This can improve scan quality.
  • MRI scans can take between 20 to 120 minutes. Our bookings team can tell you how long your scan is likely to take.

    Unfortunately we’re unable to give sedatives or painkillers. If you do need something to calm your nerves or reduce pain, please speak to your doctor in advance and follow their advice closely.

    If you’ve taken a sedative, you must bring someone with you to your appointment.

Will you need an injection?

In many cases this won’t be necessary. If you are having a scan of your abdomen or pelvis (stomach or hip area) we may give you an injection into the muscle of the leg. This helps to slow down the normal movement of the bowel during the scan and improves the image quality.

Some tests require a small injection of contrast medium (dye) into the arm or hand which contains gadolinium. This is given through a small tube called a cannula. It is not radioactive and is unlikely to cause you any after effects. It helps the doctors to tell the difference between blood vessels and other structures.
If you have an injection port (e.g. PowerPort® or Polysite®), we may be able to use this instead of a cannula. However the staff will need to see evidence of the ID card for the port to ensure that it is safe and appropriate for us to use.

The injections are given by either the radiographer or a doctor.

It is very rare to react to the contrast injection. The most common side effects, if they occur, are feeling or being sick, and this can occur soon after the injection. Please tell the radiographer if you experience any symptoms. If you experience any symptoms once you have left the hospital please contact either your GP or local Accident and Emergency department.

After the scan

Once the scan is complete you are free to leave as soon as you feel ready. You may eat and drink as normal following your scan. You will be offered an after scan information form.

Getting your results

One of our radiologists will analyse your scan. We will then send your report back to the specialist who referred you for the scan. If you do not have another outpatient appointment arranged and you do not hear anything about the results within 3 weeks, we suggest that you contact your referrer’s secretary for advice.
