Roland Richard Macharzina, Sascha Kocher, Fabian Hoffmann, Harald Becher, Thomas Kammerer, Matthias Vogt, Werner Vach, Nian Fan, Aljoscha Rastan, Franz-Josef Neumann, Thomas Zeller,

Assessment of the severity of internal carotid artery stenosis is relevant to therapeutic decisions. Direct measurement of stenosis in static three-dimensionally rendered ultrasonographic color-Doppler images after an orientation with 4-D gray-scale views (4D/3D-C-US) was recently observed to be metrically non-inferior to angiography. In the study described here, power-Doppler (Christian Doppler ... Read more >>
