Modern angiography demands frequent use of subtraction techniques. The subtraction technique has proved to be a valuable adjacent in angiography where the initial study is inconclusive because of bone structures overlapping and obscuring the contrast filled vessels. This is especially true when the contrast medium in the vessel of interest is dilute or the overlapping bone is under penetrated. In our depart, we use a Franklin rapid film changer for all cardiac and abdominal angiographic studies. The double subtraction techniques ar applied to the vertebral, cardiac and celiac angiography and obtained good results demonstrating enhanced vessel shadows, and fine abnormal tumor vessels. We used Kodak RP/SU X-Omat and Fuji subtraction film which is a single emulsion film. The first, second diapositive and final subtraction films are exposed under 30 watt bright bulb, at 180 cm distance, for 3 seconds. The exposed Kodak and Fuji films are routinely processed in Kodak RP-X-O mat pro essor.
