Abstract

The application of intravenous angiography to arteriography is currently, and justifiably, receiving much attention ^1-5 The advantages of this technique, where applicable, over the arterial approach are clear. While the application of digital equipment and procedures to intravenous angiography has stimulated interest in this technique, it should be emphasized that subtraction intravenous angiography can be performed with film-screen techniques.^6,7 The results obtained using film-screen techniques are generally superior to those which can be obtained with currently available digital systems. Although film-screen techniques are relatively simple to perform, appropriate films and photographic procedures must be used for optimum results. Care must be taken in mask production to include all the relevant data from the base film. The subtraction image should be printed on a film with contrast characteristics appropriate to the study. We will describe necessary photographic considerations for doing intravenous angiography simply and routinely with film-screen systems.
