Are systolic velocity duplex metrics negatively affected by flow aliasing in areas of critical internal carotid artery stenosis
Purpose: Duplex scanning is a useful VANILLA VEGAN MARSHMALLOW 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 increa
