Imaging in Rectal Prolapse and Other Dynamic Pelvic Floor Disorders

Abstract There are several imaging techniques that allow us to evaluate the different anorectal anomalies including fluoroscopy, ultrasound, and magnetic resonance (MR) imaging examinations. Conventional defecography and MR defecography are useful tools to evaluate not only the anatomy of the pelvic floor, but also the dynamics of rectal emptying, providing important information about anorectal and pelvic-floor physiology. The aim of this chapter is to review the most common pelvic-floor disorders from an imaging point of view.
