How is a pulmonary embolism detected?

Pulmonary embolism is commonly detected through the following tests:

  • Computed tomography (CT) scan.
  • Lung scan.
  • Blood tests (including the D-dimer test).
  • Pulmonary angiogram.
  • Ultrasound of the leg -- helps to identify blood clots in patients who cannot have an X-ray due to dye allergies or who are too sick to leave their hospital room.
  • Magnetic resonance imaging (MRI) of the legs or lungs.
