Compression ultrasound of the lower extremities is not a sensitive test for a PE, but can help with the diagnosis and with a treatment plan.
- Compression Ultrasonography , also known as a doppler of the legs is used to evaluate for a deep venous thrombosis (DVT) of the lower extremities, which can lead to the development of a pulmonary embolism. The presence of a DVT shown by ultrasonography is enough to warrant anticoagulation without requiring further V/Q or spiral CT scans. This is due to the strong association between DVT and PE. Using compression ultrasonography may also be a preferred method of evaluation during pregnancy, in which the other modalities would increase the risk of birth defects due to radiation exposure. A negative doppler scan does not rule out a pulmonary embolism, and low-radiation dose scanning may be required for a pregnant patient to further evaluate for PE.
