|  | A 
                              radiologic technique in which a fluoroscope is used 
                              to visually examine the body or an organ. (A fluoroscope 
                              utilizes an X-ray tube and fluorescent screen, with 
                              the area to be viewed placed between the screen 
                              and the tube.) This immediate imaging, when coupled 
                              with an image intensifier, is invaluable in situations 
                              such as cardiac catheterization, thin needle biopsies 
                              of tumors, and localization of foreign bodies. |  |
