WebJan 1, 2005 · BACKGROUND AND PURPOSE: Established Doppler parameters for carotid stenosis assessment do not reflect North American Symptomatic Carotid Endarterectomy … WebPreviously, we developed a new Doppler parameter, the sonographic-NASCET index (SNI), which measures carotid stenosis in a fashion more analogous to the NASCET methodology, applying the principle of mass balance to peak systolic velocities in the proximal stenotic ICA and the more normal distal ICA [20]. WebFeb 16, 2012 · The 10% NASCET classes included PSV of maximally 5% below and 4% above the class value, eg, from 55% to 64% for the 60% class. Overall, 977 of 1106 (88%) pairs could be reconstructed. The majority of missed pairs (because of identical values or clustering with insufficient graphical resolution) occurred at 0% and <30% NASCET degree … lite racer adapt 2.0 shoes
