Are systolic velocity duplex metrics negatively affected by flow aliasing in areas of critical internal carotid artery stenosis
6-Piece Dining Set Purpose: Duplex scanning is a useful noninvasive screening tool for the detection of carotid bifurcation disease.Internal carotid artery (ICA) peak systolic velocity (PSV) and ICA/common carotid artery (CCA) PSV ratios are proven metrics determining 70%-99% ICA stenosis.A potential disadvantage of using dramatically increasing sy
