3-5 Example of specific clinical procedures
Primarily used for contrast filled vessels.
DSA, an electronic technique for imaging blood vessels, is useful in diagnosing
arterial occlusion, including carotid artery stenosis and pulmonary artery thrombo-
sis, and in detecting renal vascular disease. After contrast material is injected into
an artery or vein, a physician produces images that show the difference between
the contrast-filled vessels and surrounding anatomy through an image subtraction
process.
3-6 How mode should be used
Used by or under the direction of a physician specializing in diagnostic imaging.
