The Table represents the area (in mm2) and % MR signal intensity (in I.U.) of different plaque constituents i.e. calcification, fibrous, necrotic core, and lipid core in four coronary plaques (A, B, C and D) shown in Figure 4. Combined multi-contrast ex vivo PD weighted, T1 weighted and T2 weighted MR images were used for area measurement of each constituent and its % MR signal intensity (in arbitrary units) on any of the image set showing it highest MRI visible. |
