Fig. 1 Plaque specimen removed by means of the “en bloc” method to prevent destruction of the plaque lumen.

Fig. 2 High resolution MRI sagittal section of plaque. The resolution is 200 mm, with each slice thickness also 200 mm. Cross-sectional images can be reviewed in any selected angle. In this section, invaginations and a ledge in the ICA can be seen.

Fig. 3 Plaque lumens were assigned to four categories as depicted. Top left, circular; top right, crescentic; bottom left, multi-lobular; bottom right, elliptical.

Fig. 4 The location of the bulk of plaque creating the maximal stenosis was determined to be in the CCA (top), at the bifurcation (middle), and within the ICA (bottom).

Fig. 7 The distribution of the bulk of plaque along the FDW and the NFDW of the ICA. Top: Plaque located on the NFDW. Middle: Plaque located on the FDW. Bottom: Plaque equally distributed between the NFDW and the FDW.
