CT pulmonary angiography

The best contemporary test to assess a patient suspected of having a pulmonary embolism The test uses computed tomographic imaging of the pulmonary arteries to identify blood clots in the right ventricular outflow tracts or the pulmonary arteries. The presence of a clot indicates the need for treatment with anticoagulant drugs. It is used as the generally preferred alternative to invasive pulmonary angiography (which, while accurate, requires right ventricular catheterization), or to ventilation/perfusion scanning of the lungs (which often yields indeterminate results).

CAUTION!

Potential hazards of the test include its radiation exposure, its risk for renal failure (esp. in patients with predisposing conditions for kidney injury), and the risk of allergy to the radiological contrast agent used in the test. See also: angiography
