Pelvic muscles MRI: what it can show

Pelvic floor muscles help support the bladder, bowel, and reproductive organs. MRI can show muscle size, shape, tears, scarring, and nearby soft tissues more clearly than many routine tests. It may be considered when symptoms continue, after an injury or procedure, or when examination findings need clarification. The images are interpreted alongside your symptoms and physical examination; an MRI picture alone does not explain every cause of pelvic discomfort or dysfunction.

Before the scan, describe pain with lying flat, movement, or pressure, and mention implants, pregnancy possibility, kidney disease, or claustrophobia. Follow instructions about food, drink, bladder filling, or bowel preparation. During scanning, keep still and use the intercom if you need help. Ask whether you need to relax or contract a muscle at a particular point; do not perform exercises unless the technologist instructs you.

Seek clinical advice if pelvic pain, difficulty emptying the bladder or bowel, new weakness, numbness, fever, or bleeding is worsening or limiting daily activities. After an internal preparation or contrast injection, report severe pain, heavy bleeding, breathing difficulty, facial swelling, or fainting urgently. An MRI appointment does not replace assessment when symptoms change suddenly.

Ask which pelvic muscles and supporting structures will be assessed, whether dynamic movements are included, what preparation is required, and how the findings may guide physiotherapy or other treatment.
