Why Is ABI Effective in Detecting Vascular Stenosis? Investigation Based on Multibranch Hemodynamic Model

<table>ABI for the normal case and for the stenosis cases with severities of 70% at 6 arteries, respectively. FA (femoral artery), PA (popliteal artery), PtA (posterior tibial artery), BA  (brachial artery), RA (radial artery), and UA (ulnar artery) denote the locations of the stenoses. The dotted lines represent the evaluation standards of normal ABI (0.91~1.30) proposed by ACC/AHA. Vascular stenoses may have occurred if the value of ABI exceeds this range.</table>
