title: Defecography: techniques for improved image quality.
abstract: Defecography is a radiographic study that demonstrates the physiological process involved when the rectum evacuates. Fluoroscopy, video recording and spot films are used to record the sequence of events that occur during defecation. Proper radiographic techniques and procedures must be used to demonstrate pathological conditions such as rectoceles, rectal intussusception and prolapse of the rectum.
