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].
