What is Defecography Open MRI?
A Defecography Open MRI (magnetic resonance imaging) or MR Defecography is a painless radiology exam. This is performed to examine the muscles of the pelvic floor in a non-invasive manner and find the problems related to bowel movements. This scan is also known as Dynamic Pelvic MRI and MRI of the pelvic floor, rectum, and sphincter.
In this scan, multiple images of the blood vessels, muscles, and soft tissues of the pelvic floor area are generated using radio waves and a strong magnetic field.
The MR Defecography helps doctors to understand how the rectum (the final part of the large intestine that ends at the anus) and other pelvic organs are working when a person passes stool. It also helps them to identify the cause of problems such as constipation and lack of control over bowel movement (fecal incontinence).

What Symptoms Should I Have to Get a Defecography Open MRI?
Your doctor will recommend a defecography open MRI only if you have one or more of the following ailments or symptoms because any delay could lead to serious conditions:
- Several bowel movements over a short time period
- The sensation of incomplete bowel movement
- Ongoing pain in the genitals, pelvis, or rectum
- Painful urination
- Frequent and sudden need to urinate
- Ulcers in rectum with bleeding
- Unexplained pain in the lower back
- The sensation of a mass in the vagina
- For women, pain during intercourse
What Will My Doctor Find out from a Defecography Open MRI?
A Defecography Open MRI will help your doctor:
- Evaluate unexplained pelvic pain.
- Diagnose and evaluate pelvic floor diseases and disorders that affect rectal function such as:
- Hernia (bulging in the abdomen or groin).
- Pelvic organ prolapse or rectal prolapse (a condition that occurs in women when part of the large intestine slips outside the anus).
- Find the cause of the inability to control the passage of waste material from the body.
- Find the cause of constipation (difficulty in passing waste material from the body).
- Understand how well the pelvic muscles are working during a bowel movement.
- Gather information for planning a surgery or treatment.
Your doctor may also ask you to take the Hip MRI to confirm the diagnosis for abnormalities such as cysts or tumors. Your doctor may even recommend the Arthritis Screening Panel test to evaluate rheumatoid arthritis that causes stiffness, pain, and loss of mobility in hips and other body parts. Depending on the results, your doctor will confirm the diagnosis and plan your treatment.
How Is a Defecography Open MRI Performed?
A Defecography Open MRI will help your doctor:
- Before starting the Defecography Open MRI, you will have to remove all the metal objects on your body, including eyeglasses, jewelry, hairpins, and dentures.
- A technologist will ask you to drink water 30 minutes prior to the exam.
- The technologist will then ask you to sit on an adjustable chair placed between two large magnets of an open MRI machine.
- Your doctor or the technologist will insert a gel, filled with a contrast solution, gently into your rectum (for females, a solution may also be inserted into the vagina) and will place a towel underneath you to absorb any feces or urine that may leak out during the exam.
- Then the technologist will wrap an imaging coil (containing sensors) around your pelvic area and will take multiple images of your pelvic area.
- At certain points during the scan, the technologist will ask you to hold in or expel the gel solution as you would while passing stool. These images will be displayed on a monitor.
- The technologist will also take images when your pelvic floor muscles are relaxed.
- Make sure you don’t move during the scan as any movement can blur the images.
What Should I Expect After Completing Defecography Open MRI?
- Some people might feel mild cramping or bloat from the air that enters the rectum when the contrast gel is inserted. This feeling will reduce each time they pass gas.
- Otherwise, there are no restrictions placed upon you after taking the test. You can go back to your regular activities like driving and eating regular food unless otherwise directed by your doctor.
How Long Does a Defecography Open MRI Take?
An MR Defecography is usually completed between 30 to 45 minutes.
Is Radiation Involved in a Defecography Open MRI?
No. An MRI is a painless imaging test that doesn’t use radiation.
Are There Any Risks in Taking a Defecography Open MRI?
- People who have implants such as a cardiac pacemaker, coronary stent, orthopedic rods, and plates, which contain metal, may face certain risks. The magnets used in an MRI can make implanted pins or screws move in the body or cause problems with pacemakers.
When Will I Receive My Results?
