MRI - Perineum
MRI has very high contrast resolution, which means that it can see the different layers of the bowel wall and surrounding structures. It also is able to use different sequences to specifically look for any small areas of inflammation within the bowel or more commonly the deeper structures.
This means that the surgeon has more information and understanding of the anatomy when you have an examination / treatment under general anaesthetic.
We use MRI perineum to assess pain in this area especially if there is a small opening or a history of inflammatory bowel disease e.g Crohns disease. Its superior contrast resolution means that high quality imaging can be obtained in the small area.
Is there any preparation needed beforehand?
No preparation is required for the MRI perineum.
What does an MRI scan involve?
You will be asked to remove some of your clothes and wear a hospital gown. You will be asked a series of questions to ensure that it is safe for you to have the examination and you will need to remove anything metal. The Radiology staff will take you to the MRI machine which is a little like a tunnel. The MRI is very noisy and you will be given earmuffs. You can bring a CD to listen to if you would like. The examination takes about 40 minutes.
