Comparison of location-matched transversal images obtained from the “SPACE STL”, “SPACE SWL+SG”, and “SPACE SWL” scans, respectively, in an 18-year-old female volunteer. Shown are three 2-mm-thick MPR images located below, at, and above the carotid bifurcation (arrows and star symbols), which are reconstructed from the 3D image sets. Swallowing was shown to induce severe overall image degradation, obscure wall boundary, and reduce the wall-to-background contrast. The proposed SG approach significantly mitigated the above problems and provided good artery wall delineation and high wall-to-background contrast, which is comparable to “SPACE STL” imaging. All images are displayed with the same window level. *, external carotid lumen; **, internal carotid lumen.
