Abstract
Digital Subtraction is a computerised radiological technique to demonstrate the vascular tree by removing unwanted background information and enhancing dilute contrast medium within the blood vessels. Contrast may be introduced intravenously or intra-arterially. The relative merits of these two methods, together with the advantages and limitations of the technique are discussed.
