During a fluoroscopy procedure, continuous x-ray beams are passed through the body. The images are transmitted to a monitor so that the body part and its motion can be seen in detail (like an x-ray movie). It is used to diagnose or treat patients by displaying the movement of a body part or of an instrument or dye (contrast agent) through the body. Common indications to use fluoroscopy at Veterinary Specialists of Alaska, P.C. are evaluation of blood flow in patients with portosystemic shunts (a disease in which blood flows around the liver rather than through it), or to diagnose and treat esophageal strictures. When fluoroscopy is medically necessary, the lowest possible exposure for the shortest possible time is used.
