    CT-Angiography
     

    MIP-Visualization of the right carotid bifurcation showing severe stenosis of the ICA.

     
    Area of Interest: unknown; Imaging Technique: CT-Angiography;

    Curved MPR demonstrates both the residual lumen and the intraluminal soft plaque.

     
    Area of Interest: unknown; Imaging Technique: CT-Angiography;

    Direct volume rendering illustrates the carotid stenosis in relation to the bony structures of the skull.

     
    Area of Interest: unknown; Imaging Technique: CT-Angiography;

    Axial slice image allows a precise evaluation of the degree of stenosis of the right ICA (arrow).
