Digital subtraction angiography (DSA) is a fluoroscopic technique used for visualizing the blood vessels with the help of contrast dye. This procedure eliminates the bone and cartilage from the image so that it provides an accurate view of blood vessels. DSA helps to detect a problem with the blood flow.
