Your doctor has asked that you have a MR Enterography. Magnetic Resonance Imaging
(MRI) is a safe and painless way for your doctor to look at your abdomen and small
bowel. The pictures can help your doctor find out more about the problems you are
having. The test uses radio waves and a magnetic field to take pictures.
This test will take about 2 hours to complete. During the first hour you will drink a
special contrast called Volumen. This contrast will swell your small bowel which will
help the radiologist check your abdomen. We will also start an intravenous line (IV) that
will be used later in the test.
Before your MR Enterography
ξ Do not eat for 4 hours before your MRI so that your small bowel will be empty.
ξ Tell your doctor or the nurse in MRI if you are allergic to any medicine or
ξ If you take medicines, you may take them the day of the test.
ξ If you wear any kind of medicine patch, it will need to be taken off before the test.
Bring a new patch that you can put on after the test.
ξ If you have a fear of small spaces, talk to your doctor. Your doctor can give you
some medicine that will help you relax. If you do bring medicine to help you
relax, you will need to have someone with you that can drive you home.
ξ If you have had an endoscopy or a colonoscopy in the last 8 weeks, please call the
MRI nurses office (608) 262-5276.
Day of Test
ξ Take the Atrium elevators to the third floor Radiology Check-In desk. The MRI
area will be informed that you have checked in.
ξ Plan to arrive 1 hour before your MRI. There are many questions we need to ask
about your health history. Please bring cards for any implants in your body.
ξ After we bring you to the MRI area, you will be given an oral contrast called
Volumen. You will be asked to drink this contrast over 1 hour. You may go to
the bathroom at any time before the MRI.
ξ You will need to remove all metal items such as a watch, hairpins, bra, jewelry
and coins. You may not bring anything into the room with the MRI machine.
This includes your wallet, purse, cell phone and keys
ξ We may ask you to change into hospital clothing. A locker will be provided for
your clothes and any other items.
ξ An intravenous line (IV) will be started. During the test we will use this IV to
inject two medicines:
1. Glucagon. This medicine will be given by the nurse to slow down the
movement of the bowel. You will need 2 doses of this medicine because
it does not last very long.
2. Gadolinium is a contrast medicine. This is used to highlight blood vessels
near the end of the MRI.
During the Test
ξ A MRI is a long tube-like machine that is open on both ends. You will lie on a
padded table in the middle of the machine. We will ask if you can lie on your
stomach as this position separates the loops of the bowel so that we get a better
picture. If you are unable to do this we can also do this study on your back. We
will try to make your position as comfortable as possible. A coil will be placed
on your stomach or your back. The coil works like an antenna to help us get our
ξ During the test you will hear the MRI machine make very loud knocking sounds.
You will have headphones to block out some of this noise. You will also be able
to listen to music. You will also hear the technologist instruct you on how to
ξ The technologist will not stay with you in the room. You will be able to hear and
see the staff through the intercom and window. They will take pictures and check
on you during the test. Tell us if you feel uncomfortable at any time.
ξ We will place a ball in your hand to squeeze if you need the technologist during
ξ At different times during the test you will be asked to hold your breath for about
15 to 20 seconds.
ξ It is important that you try not to move during the test. It is just like taking a
picture with a camera. If you move while the picture is being taken, the picture
will be blurry.
ξ During the test, a nurse or the technologist will come into the room and give you
the Glucagon medicine that slows the motion of your bowel. After the second
dose of Glucagon you will be given the IV contrast to highlight your bowel.
ξ The nurse and the technologist will leave the room and take a few more pictures
before your test is done.
After the MR Enterography Test
ξ Your IV will be removed after the MRI is complete.
ξ Within the first hour after your test, you may feel an urgent need to go to the
bathroom. Some patients get diarrhea after drinking the Volumen. The diarrhea
may last a short time, but plan carefully for the ride home.
ξ We also would like you to drink plenty of fluids to help your system clear the
ξ Your MRI will be read by a radiologist and the results will be sent to your doctor.
Your doctor will share the test results with you.
ξ If you have any problems or concerns after your test, please call your doctor.
