DSA is a radiologic technique that allows for clear visualization of blood vessels in a bony or dense soft tissue. The process begins with routine digital X-ray or MR imaging of the target tissue. This is followed by the injection of contrast material into the vascular and additional X-ray or MR images. The first set of images are referred to as the “mask” studies and are subtracted from the injection studies leaving the images of the vascular tree free of the tissue of its environment (Fig. 1).
