==Overview== Compression ultrasound of the lower extremities is not a sensitive test for a PE, but can be diagnostic and can aid with a subsequent treatment plan.
- Compression Ultrasonography , also known as a doppler of the legs is used to evaluate for a deep venous thrombosis (DVT) which often leads to the development of a pulmonary embolism. The presence of a DVT, as shown on ultrasonography of the legs, itself 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 oreferred 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.
