In addition to the angiography of the heart, angiography can also be used to
detect blockages or other problems in the arteries and veins of the arms and
legs (peripheral) and kidneys (renal), as well other areas of the body. This
X-ray test takes pictures of the blood flow within the artery. A catheter is
introduced into an artery, usually the leg, and guided into the artery that
is being evaluated. Contrast medium is injected to make the vessel visible
on the X-ray. Images of the contrast medium as it flows through the area of
interest are recorded, allowing doctors to see if the arteries are narrowed
or blocked, or to detect the presence of blood clots or
aneurysms.
