Shear wave elastography (SWE) was performed independently by two radiologists in 264 solid breast masses. The images were reviewed for color overlay pattern (COP) classification by the two radiologists, double blinded to any information. The interobserver agreement of the COP was almost perfect (κ=0.908) and high in E (ICC=0.89). The AUC value of the COP (0.954) was significantly higher than that of E (0.915) (p=0.002) but not significantly different from that of E combined with COP (0.957) (p=0.098). The SWE color overlay pattern and E of breast masses were highly reproducible. The COP had better diagnostic ability than E, suggesting that COP may be a more reliable parameter for solid breast mass evaluation.
两名放射科医生对264例乳腺实性肿块独立进行剪切波弹性成像（SWE）检查。两位放射科医生对图像进行彩色叠加模式（COP）分类评估，且对任何信息均实行双盲。COP的观察者间一致性几乎完美（κ=0.908），而在弹性值（E）方面一致性较高（组内相关系数ICC=0.89）。COP的曲线下面积（AUC）值（0.954）显著高于E的AUC值（0.915）（p=0.002），但与E联合COP的AUC值（0.957）无显著差异（p=0.098）。乳腺肿块的SWE彩色叠加模式和E具有高度可重复性。COP比E具有更好的诊断能力，提示COP可能是评估乳腺实性肿块更可靠的参数。
