Does MRI show rectal prolapse?
Would an MRI diagnose a rectal prolapse?

Re: Does MRI show rectal prolapse?
I believe the test is called a Dynamic MRI, or a defecography. I have not had this test done yet. My Rectal/Colon Specialist was able to determine that I have a prolapse with a digital exam. A bit more info below:

A defecating proctogram is a study commonly used to demonstrate the functional problem in a person with pelvic floor dysfunction. During this study, the patient is given an enema of a thick liquid that can be detected with x-ray. A special x-ray video records the movement of the pelvic floor muscles and the rectum while the individual attempts to empty the liquid from the rectum. Normally the pelvic floor relaxes allowing the rectum to straighten and the liquid to pass out of the rectum. This study will demonstrate if the pelvic floor muscles are not relaxing appropriately and preventing passage of the liquid.

The defecating proctogram is also useful to show if the rectum is folding in on itself (rectal prolapse). Many women have outpouching of the rectum known as a rectocele. Usually a rectocele does not affect the passage of stool. In some instances, however, stool may become trapped in a rectocele causing symptoms of incomplete evacuation. The defecating proctogram helps to identify if liquid is getting trapped in a rectocele when the individual is trying to empty the rectum."

Re: Does MRI show rectal prolapse?
Just to let you know my opinion based on my situation ..

I had a proctogram which clearly identified an intussusception. Was due to have surgery to fix it, but they sent me for a dynamic MRI to get a clearer picture. The Dynamic MRI did not show any intussussception or prolapse, so surgery was cancelled which was devastating for me because my symptoms and problems are very debilitating and affect my life hugely. So now I am waiting to have a internal exam under anaesthetic to see if that helps with a diagnoses. I have done some research on the web and some doctors feel that an intussussception or prolapse can be more prominent some days than other days and that sometimes an MRI scan may not clearly show it. Also, it depends alot on the radiographer who reads the MRI and their expertise in this area.

I will be very interested to see what other people on this forum think about this. I am just so anxious to have a diagnosis so that I can move on to getting it fix and returning to a normal life.
