Shown are two plaque types with different plaque scores. The left plaque would be classified as stenosis < 40%; intermediate echogenicity; heterogenous texture and irregular surface. Plaque score: 4; reversed score: 4. The right plaque would be classified as stenosis <40%, low echogenicity, homogeneous texture and smooth surface. Plaque score: 1, reversed score: 4.
