Duplex ultrasound is a specialized interpretation of ultrasound waves and an integral tool in medical diagnosis and therapy today. Duplex ultrasonography combines the principles of anatomic and flow ultrasonography to deliver diagnostic information to the interpreter[1]. Doppler ultrasonography refers to the utilization and application of the Doppler effect to sound wave information to interpret movement or flow within tissues[2]. It is important to have a basic understanding of the technology and related physical principles to read and interpret duplex ultrasonography. These principles include the Doppler effect, electronic gating, and varying methods of wave generation[3].
