Chest X-ray: A chest x-ray gives the detailed image of your lungs, heart as well as ribs.
Electrocardiography (ECG): An ECG will measure the heart’s electrical activities.
Magnetic resonance imaging (MRI): MRI produces a detailed image of internal structures by using radiofrequency and magnets.
CT scan: A computed tomography (CT) scan gives the cross-sectional images of the lungs.
Pulmonary angiography: In this test, your doctor can guide specialized tools through your veins by making an incision, and they will also inject a special dye so that the blood vessels of the lung can be visualized.
Duplex venous ultrasound: This test uses sound waves to see the blood flow and to check the blood clots in your legs.
Venography: In this procedure X-ray of the veins is taken after injecting dye by using a catheter (long plastic tube).
Another diagnosis of pulmonary embolism includes-
Blood tests:
Your doctor may advise a blood test to check the clot-dissolving substance called D dimer. High levels may indicate an increased likelihood of blood clots, though other factors can also cause higher levels of D dimer.
Blood tests are also giving the measurement of the amount of carbon dioxide and oxygen in your blood. A clot in a blood vessel of your lung can cause a low oxygen level in your blood.
Additionally, blood tests are also used to determine whether you have an inherited clotting disorder.
