MRI Small Bowel (Enterography) Information

An MRI scan of the small bowel is a specialised imaging test used to examine the small intestine. The scan uses a strong magnetic field and radio waves to produce detailed images of the bowel and surrounding organs. MRI does not use X-rays or radiation and is considered a safe and painless test. It is commonly used to investigate conditions such as inflammation, bleeding, strictures, or diseases affecting the small intestine, including Crohn’s disease.

Safety

It is necessary that you inform the Imaging Team before your arrival if you have any implants, or have answered yes to any of the safety questions, as an MRI may not be suitable for you and post a safety risk.

Before the scan

You will be asked to avoid eating for about six hours before your appointment, although you may still drink small amounts of clear, still, fluids.

You will be asked to arrive one hour before your scan. During this time you will be asked to drink a preparation drink, called Klean-Prep. This liquid helps fill and highlight the small bowel so that it can be seen clearly on the MRI images.

The drink may have a mild laxative effect, and you may experience bloating, stomach cramps, or the need to use the toilet.

During the scan

A small plastic tube called a cannula will usually be inserted into a vein in your arm or hand. This allows the team to administer:

Buscopan – a medication that relaxes the bowel muscles and reduces movement in the intestine. This helps produce clearer images.
MRI contrast (gadolinium) – a special dye that improves the visibility of tissues and blood vessels on the scan.

You will lie on a scanning table and a special piece of equipment called a coil will be placed around your abdomen. The table will then move into the MRI scanner, which is a short, open-ended tunnel.

The scanner produces loud tapping or knocking sounds while images are taken. You will be given headphones to reduce the noise and allow communication with the radiographer.

The MRI scan will last for approximately 45 minutes and during this time you will be asked to keep still and follow some simple breathing instructions.

After the scan

Once the scan is finished, the cannula will be removed and you will usually be able to go home shortly afterwards. The preparation drink may cause diarrhoea or abdominal discomfort for several hours, so you may wish to stay close to a toilet and drink plenty of fluids. You are able to eat as normal.

When will the scan be reported?

Your scans will be reported by a Consultant Radiologist and made available to your referring Consultant/GP routinely with in 48 hours.

Cancellations

If you are unable to attend your appointment, 48 hours’ notice is required to cancel or rebook otherwise you may be charged the full cost of the appointment.

Personal Belongings

Patients are responsible for their own belongings at all times. As you may be asked to remove jewellery it is preferred that these are not worn to your appointment.

Children
