Screening Examinations

Fluoroscopy and angiography are special applications of X-ray imaging. A fluorescent screen and image intensifier tube are connected to a closed-circuit television system; this allows real-time imaging of structures in motion or augmented with a radiocontrast agent. Radiocontrast agents are usually administered by swallowing or injecting into the patient’s body to delineate the anatomy and functioning of the blood vessels, the genitourinary system or the gastrointestinal tract (GI tract). 

Two radiocontrast agents are presently in everyday use. Barium sulphate is given orally or rectally for evaluation of the GI tract. In multiple proprietary forms, Iodine is given by oral, rectal, intra-arterial or intravenous routes. These radiocontrast agents strongly absorb or scatter X-rays and, in conjunction with real-time imaging, demonstrate dynamic processes, such as peristalsis in the digestive tract or blood flow in arteries and veins. Iodine contrast may also be concentrated in abnormal areas more or less than normal tissues and make abnormalities (tumours, cysts, inflammation) more conspicuous. Source: Wikipedia
