Typical imaging findings for each of the four groups at the level of the carotid bifurcation on CTA, 3D MEDIC and T1wBB, described in Table 4. The color representation for each of the four groups are the same as in Table 4. In panel A, in blue color, the arrow indicates a large non-calcified plaque component with signal loss on 3D MEDIC and elevated T1w signal (3DMEDIC + /T1w +). In panel B, in yellow color, the arrow indicates a non-calcified plaque component with no signal loss on 3D MEDIC and elevated T1w signal (3DMEDIC-/T1w +). The dotted arrow indicates a calcification, with high attenuation on CTA, signal loss on 3D MEDIC and signal loss on T1w. In panel C, in green color, the filled arrows on both sides indicate large non-calcified plaque components with signal loss on 3D MEDIC and no elevation of Tw1 signal (MEDIC + /T1w). The dotted arrow on the left side indicate a calcification, with high attenuation on CTA, signal loss on 3D MEDIC and signal loss on T1w on the asymptomatic side (this side was not included in final image analysis). In panel D, in white color, the arrow indicates a small non-calcified plaque without signal loss on 3D MEDIC and no T1w signal elevation (MEDIC-/T1w-)
