B-flow Ultrasonography of Peripheral Vascular Diseases

B-flow ultrasonography (US) is a new US technology, which has recently been utilized for the investigation of vascular diseases. In this pictorial essay, we demonstrate the B-flow US imaging presentations of various peripheral vascular diseases, including diseases of the carotid artery, peripheral artery, peripheral vein, and hemodialysis fistula. B-flow US is superior in the depiction of complex hemodynamics in the blood spaces of peripheral vascular diseases. Discrimination between flowing blood and surrounding stationary structures (vessel wall, thrombus, hematoma, intimal flap, venous valve) can be made without difficulty by using B-flow US. Our experiences show that B-flow US is a useful technique in the diagnosis of peripheral vascular diseases.
