Quantitative Ultrasonography Techniques for Assessing Femoropopliteal Atherosclerotic Lesions Using Peak Systolic Velocity Ratio: The TURN-UP Study II.
PURPOSE Peak systolic velocity ratios (PSVRs) measured by duplex ultrasound (DUS) are commonly used to evaluate arterial stenosis in patients with lower extremity artery disease. However, standardized measurement protocols have not yet been established. Although guidelines recommend setting the angle correction to 60°...
