Figure 5

shows axial (A) and sagittal (B) reformatting of a right ICA bulb stenosis with large plaque ulcer/uplifted plaque. The larger solid arrow shows the reduced ICA lumen at the stenosis, readily measured by CT caliper tool, more accurate from the axial source image. The dashed arrow indicates the ulcerated plaque and small arrow the ECA. Picture reproduced with permission from AJNR [13]. The thin axial source images are used for measurement as they have the highest spatial resolution.
