Cine Defecography
A test of the motion of the pelvic floor, the muscles which control a bowel movement, and the motion of the anus and rectum during a bowel movement. A small amount of thickening barium is placed in the rectum while a video recording is made using fluoroscopy as you expel the barium. Contrast may also be placed in the vagina of female patients to better define movement of the rectum toward the vagina.
Fluoroscopy is an imaging technique that uses X-rays to obtain real-time moving images of the interior of an object. In its primary application of medical imaging, a fluoroscope allows a physician to see the internal structure and function of a patient, so that motion can be watched.
