It takes 30-60 minutes
Pulmonary angiography is usually performed in a hospital's radiology department
It is examination of pulmonary arteries using a contrast medium.
the guide wire and catheter are inserted into a vein instead of an artery, and are guided up through the chambers of the heart and into the pulmonary artery
to evaluate blood circulation to the lungs. It is also considered the most accurate diagnostic test for detecting a pulmonary embolism.
A D-dimer test can be done to show if the body is breaking down a blood clot. If this test shows positive then a spiral CT scan can be done to try to pinpoint the clot. Also a V-Q (ventilation-perfusion) scan can be done to pinpoint an area of the lung that is not getting blood flow. Regardless of the exact location the clot must be removed, either by surgical excision or by "clot buster" drugs such as streptokinase.
