Digital subtraction angiography (DSA) is a radiographic or fluoroscopic technique which is used for the diagnosis of various vascular disorders. The technique is also utilized for the visualization of blood vessels in the soft dense tissue environment or a bone. Digital subtraction angiography is applied for obtaining clear images of the arteries and is also highly effective in contrasting arterial structures with the surrounding bone and tissue material. Digital subtraction angiography has proven to be efficient in the identification of abnormalities such as ulcerated plaques, stenosis, occlusions and aneurysms.
