Dynamic Pelvic Floor MRI + MR Defecography
When the pelvic floor muscles and ligaments supporting a woman’s pelvic organs weaken, the pelvic organs can drop out of place. This is a common condition called pelvic organ prolapse. Most women develop prolapse after menopause, childbirth, or hysterectomy. It can be debilitating as well as embarrassing and can significantly impact the quality of life. The most common symptoms of pelvic organ prolapse are urinary incontinence, incomplete bladder emptying, pelvic pain, constipation, obstructed and difficult defecation, and fecal incontinence.
A breast MRI is used in conjunction with other imaging studies, such as mammography and breast ultrasound, to provide a more detailed evaluation of breast tissue. It is performed to assess the extent of breast cancer and to screen for breast cancer in women who are considered to be at high risk for the disease.
What is Dynamic Pelvic Floor MRI + MR Defecography?
Until recently, fluoroscopic defecography was used for pelvic floor imaging, which exposed patients to radiation (x-rays). With rapid advances in MRI technology, both functional and anatomic evaluations can be performed in a single examination without using radiation. MRI allows us to image in any plane, free from the confusion of overlying structures, and can detect structural abnormalities such as tumors, abscesses, hernias, and defects or lesions in the pelvic floor muscle. These findings can help you and your doctor plan for the best clinical treatment or surgery.
What are the benefits of Dynamic Pelvic Floor MRI
+ MR Defecography?
- Provides real-time visualization of pelvic floor muscles and organ movement during various functional maneuvers.
- Accurately assesses pelvic floor disorders including prolapse, rectocele, enterocele, anismus, and incontinence.
- Offers superior soft-tissue detail compared to traditional fluoroscopic defecography.
- Helps pinpoint the exact cause of pelvic pain, pressure, or bowel dysfunction for more targeted treatment.
- Completely noninvasive and radiation-free, making it a safe diagnostic option.
- Allows evaluation of multiple pelvic compartments, giving a comprehensive view of overall pelvic floor function.
- Guides treatment planning for urogynecology, colorectal surgery, and pelvic floor physical therapy.
Frequently Asked Questions
Part 1 of the MRI Exam
We acquire static MRI images at multiple planes through your pelvis for an anatomic evaluation of pelvic floor structure and pelvic organs including the uterus, ovaries, vagina, bladder, urethra, and anorectum.
Part 2 of the MRI Exam
The MRI technologist will then help you through the next few steps:
- You will be asked to perform Kegel exercises while images are taken. This is when you tighten the pelvic floor muscles, similar to stopping the urine flow while urinating.
- You will be asked to perform the Valsalva maneuver by taking a deep breath and bearing down without letting the gel out while images are taken. You may be asked to repeat this step.
- You will be asked to perform defecation while images are taken. You will take a deep breath and bear down towards the rectum and push the contrast gel out of the rectum. You may be asked to repeat this step.
