“…20,24,33,37,50,52,62 The sensitivity of DUS ranged from 80% (specificity 96%) to 98% (specificity 94%). The specificity ranged from 89% (sensitivity 88%) to 99% (sensitivity 92%).…”

“…[3][4][5] Duplex ultrasound (DUS) is a noninvasive technique for evaluation of peripheral vascular disease and previous studies have shown good agreement between DUS and DSA. [6][7][8][9][10][11][12][13] It is easy to perform, has no side effects, and is relatively inexpensive. 14 However, DUS is operator-dependent and there are concerns about reproducibility of results on different equipment.…”

“…These studies used uniplanar angiography as the gold standard, which can underestimate the severity of lesions. 6,7,11 The goal of this study was to assess the agreement between DUS and multiplanar DSA in detecting de novo femoropopliteal lesions. Furthermore, we sought to suggest PSV and Vr criteria for identifying and grading femoropopliteal lesions with high accuracy.…”

“…The PSV ratios are directly related to the changes in cross-sectional area but not to the amount of volume flow. 21 Moreover, they reflect the hemodynamic changes in a significant TRAS so that they cancel interindividual variability of blood flow velocities such as that in the renal artery PSV.…”
