Duplex Sonography versus Angiography for Assessment of Femoropopliteal Arterial Disease in a “Real-World” Setting

Abstract

Agreement between DUS and DSA in the femoropopliteal segment is only moderate with respect to the absolute degree of stenosis. However, detection of a >50% stenosis can be done with acceptable precision in routine clinical practice using PSVR>2.4 as a threshold.
