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.
