Digital subtraction arteriography.
DSA has quickly made the transition from an experimental examination performed in a research institution to a routine procedure performed in a community hospital. Diagnostic quality images for screening applications are obtained in over 90% of patients, and in many instances DSA is the only angiographic study that need be done. The applications of IV DSA have broadened to encompass many angiographic procedures for which selective injections are not mandatory. When IA studies must be performed, digital equipment offers the advantages of speed, safety, and lessened patient discomfort. New technological developments will increase the advantages and applications.
