Compression ultrasonography, also known as a Doppler study of the legs, or lower extremity noninvasive studies (LENIS) is used to evaluate a patient for the presence of [[deep venous thrombosis]] (DVT) in the lower extremities, which can lead to the development of a pulmonary embolism. The presence of a [[deep venous thrombosis|DVT]] shown by [[ultrasonography]] is enough to warrant [[anticoagulation]] without a V/Q or spiral CT scans. The decision to anticoagulant patient with a positive compression ultrasound is due to the strong association between deep vein thrombosis and subsequent pulmonary embolism. Compression ultrasonography is also a preferred method of evaluation during [[pregnancy]], a time during which the other modalities would increase the risk of birth defects due to radiation exposure. A negative compression ultrasound does not rule out a pulmonary embolism, and an additional low-radiation dose scanning may be required in a pregnant patient to further rule out pulmonary embolism. | Compression ultrasonography, also known as a Doppler study of the legs, or lower extremity noninvasive studies (LENIS) is used to evaluate a patient for the presence of [[deep venous thrombosis]] (DVT) in the lower extremities, which can lead to the development of a pulmonary embolism.

Overview
Compression ultrasonography, also known as a Doppler study of the legs, or lower extremity noninvasive studies (LENIS) is used to evaluate a patient for the presence of deep venous thrombosis (DVT) in 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 a V/Q or spiral CT scans. The decision to anticoagulant patient with a positive compression ultrasound is due to the strong association between deep vein thrombosis and subsequent pulmonary embolism. Compression ultrasonography is also a preferred method of evaluation during pregnancy, a time during which the other modalities would increase the risk of birth defects due to radiation exposure. A negative compression ultrasound does not rule out a pulmonary embolism, and an additional low-radiation dose scanning may be required in a pregnant patient to further rule out pulmonary embolism.
