Dynamic Pelvic MRI Procedure Information

Your doctor has recommended a dynamic pelvic MRI for you. Magnetic resonance imaging (MRI) uses a magnetic field, radio waves and a computer to create detailed image slices (cross sections) of the pelvic floor. Dynamic MRI is used to diagnose prolapse, incontinence, pelvic pain or constipation, and allows for a rapid evaluation with greater patient comfort than previous studies used to evaluate such conditions. Dynamic pelvic MRI provides a three-dimensional image. Our team of expert physicians, nurses and technologists is headed by Rola Saouaf, MD, chief, Body MRI.

Before Arriving for Your Exam

  • You can print and fill out the MRI Questionnaire and the MRI and Pregnancy form, if applicable, from the Pre-Registration Questionnaire page before arriving to speed the registration process.
  • If you are claustrophobic (fearful of small, enclosed areas) or experience pain when lying on your back for more than 30 minutes, your referring physician may prescribe a relaxant or pain medication to help you through the exam. The imaging physicians at Cedars-Sinai will not prescribe these medications for you.
  • If you plan to take relaxation medication before you exam, it is our policy that you come with someone who can drive you home.
  • For studies that involve IV contrast: If you have veins that are small or hard to find, or have a port, please arrive 60 minutes before your scheduled arrival time.
  • You must empty your bladder two hours before the exam and not void again until the exam is complete. 
  • No fasting is required for this study.
  • If your doctor gave you an order, please bring it with you.
  • We want to make your waiting time as pleasant as possible. Consider bringing your favorite magazine, book or music player to help you pass the time.
  • You may select an Internet radio station to provide music for you.
  • Please leave your jewelry and valuables at home and wear comfortable clothing.

After Arriving

  • You must tell the technologist, radiology nurse and/or imaging physician of any allergies you may have.
  • You will be asked to fill out a questionnaire which will determine if an MRI is safe for you. People with various implants (usually metallic), body piercings or with metal in their bodies may have difficulty with an MRI, which uses a strong magnetic field.

During Your Exam

  • You will be asked to change into a hospital gown, and remove any metallic objects.
  • You will lie on the scanning table head first with arms at your side.
  • Coils, which act like antennae, will be placed around your pelvis to improve the images obtained.
  • The scanning table will slide your whole body into the magnet.
  • During the scan you will hear intermittent humming, thumping, clicking, and knocking sounds. Earplugs will be provided to help mask the noise and allow you to listen to music.
  • As pictures are taken, you must hold very still at times.
  • The technologist is always able to see and hear you during the exam.

For Dynamic Pelvic MRI Defecography

  • Our goal is to make the exam as comfortable for you as possible, while obtaining the images we need to diagnose your condition.
  • A soft gel-like substance that acts like a contrast material will be placed in you rectum. A cloth will be placed under you to absorb anything that may leak out during the exam.
  • You will be asked to lie on your back with your knees bent on a moveable exam table. If you need help, we can use bolsters and straps to help you remain still while in the correct position as the images are taken.
  • A device called an MR coil will be strapped around your pelvis. The coil helps improve the quality of the images.
  • Images will be taken as you contract your muscles as you would during a bowel movement (Valsalva), as well as when your muscles are relaxed.
  • During the exam, a technologist will give you instructions. The technologist will be able to hear and see you at all times.
  • The exam will take approximately 15-20 minutes.

After Your Procedure

  • There are no restrictions placed upon you. You may eat or drive as normal, although if you took relaxation medication, you will need someone to drive you home.
  • Your films will be examined by an imaging physician and a report sent to your doctor. Your doctor will review the results with you.
  • To request a copy of your images or your report, please call 310-423-8000, option 2 or submit an online request.
