MRI DEFECOGRAPHY

MRI Defecography is a non-invasive test that uses magnetic resonance imaging to evaluate how well pelvic muscles are functioning during various stages of a bowel movement or to assess pelvic floor disorders.

How is the procedure performed?

You will be asked to change into a hospital gown and remove any metallic objects. You will be asked to empty both your bladder and bowels prior to getting on the scanner table, prior to being positioned on the scanner table. A soft gel that acts as a contrast material will be placed in your rectum. You will be positioned on the MR exam table lying on your back with your knees bent. A towel will be placed under you to absorb any urine or feces that may leak out during the exam. A device called an MR coil will be strapped around your pelvis. This coil helps improve the quality of the images.

Images will be obtained as you contract your muscles as you would during a bowel movement, including squeezing, straining and defecating. Images will also be taken while your muscles are relaxed. The MRI technologist will give you instructions throughout the exam.

You will need to arrive 30 minutes before your scheduled exam time. The actual exam takes approximately 45 minutes.
