The post-processing concept for the semi-automated assessment of carotid wall thickness and lumen diameter is shown exemplarily in a patient with a calcified plaque in the carotid bulb. a Reconstructed longitudinal view of the carotid bifurcation based on a 3D-black-blood T1 weighted CMR-image with the standardized position of the eight analysis planes (see Fig. 2). b Manual segmentation of outer (brown line) and inner (blue line) vessel wall border in the cross-section corresponding to the red line. c Quantitative results of vessel lumen (inner ring labeled blue) and of wall thickness (outer ring labeled yellow to red) are displayed in a bulls-eye-plot comprising 12 evenly distributed wall segments
