Table 3 The classifications of lipid percentage index (LPI) and cap thickness index (CTI) for vulnerable plaque
LPI | The range of lipid percentage | CTI | The range of Min cap thickness |
|---|---|---|---|
0 | LP = 0% (no lipid) | 0 | No lipid |
1 | 0% < LP < 5% | 1 | MinCT > 0.3 mm |
2 | 5% ≤ LP < 15% | 2 | 0.20 mm < MinCT ≤ 0.3 mm |
3 | 15% ≤ LP < 25% | 3 | 0.065 mm < MinCT ≤ 0.2 mm |
4 | 25% ≤ LP < 100% | 4 | MinCT ≤ 0.065 mm |
