A Defecography is a fluoroscopy test of the rectum. It shows rectal emptying and pelvic floor movement. Typical effective dose 1 to 3 (fluoroscopy) or none (MRI) mSv, similar to up to about 1 year of natural background radiation (about 3 mSv a year).
General health information, not a diagnosis. In an emergency, call 102. Always consult a qualified health professional.
Rectal emptying and pelvic floor movement.
