Angiography / Venography. Angiography and Venography are specialized X ray exams of the arteries and veins to diagnose blockages and other blood vessel problems. One of the most common reasons for Angiograms is to see if there is a blockage or narrowing in a blood vessel that may interfere with the normal flow of blood through the body.
Sep 01 2004 Computed tomographic CT pulmonary angiography is becoming the standard of care at many institutions for the evaluation of patients with suspected pulmonary embolism.
