    3D reconstruction with (a) and without (b) axial plane perpendicular to lumen of the ICA. Yellow color represents thrombus/non-calcified plaque and white color represents calcification. At the axial slide the red arrows indicates the point of maximal stenosis (c) and the distal normal portion (d) of the ICA.

  • Image Result
    Diagram showing relevant landmarks and cut-off points for analysis of the ICA: point of maximum stenosis (A), proximal (B) and distal (C) volume cut-off 2mm from point of maximum stenosis and normal a

    Diagram showing relevant landmarks and cut-off points for analysis of the ICA: point of maximum stenosis (A), proximal (B) and distal (C) volume cut-off 2mm from point of maximum stenosis and normal appearing portion of distal ICA (D). Volumetric analysis is based on the volume between A and C.

  • Image Result
    PSV plotted against the percentage stenosis measured with CTA volumetric measurement using the ECST method. ^=significant correlation.
