Testing for venous blood clots. Venous blood clots may be detected in a variety of ways, though ultrasound is most commonly used. Occasionally, the patient's size and shape limit the ability for ultrasound to provide a definitive answer. Venography is an alternative test to look for a clot.
DVT and pulmonary embolism are both treated with the same medicines. Spiral CT scan or CT angiogram. Doctors use this test to look for blood clots in your lungs and in your legs. Dye is injected into a vein in your arm to make the blood vessels in your lungs and legs more visible on the X-ray image. While you lie on a table, an X-ray tube rotates around you, taking pictures from different angles. This test allows doctors to detect pulmonary embolism in most patients.
