| 目的 探讨乳腺局灶性病变三维剪切波弹性成像（3D-SWE）图像质量的影响因素。方法 对187例乳腺局灶性病变患者行3D-SWE成像，并按图像质量分为1级（非常满意）、2级（基本满意）和3级（不满意）。分析操作有无附加压力、乳腺分型、耦合剂厚度、病变位置、大小、深度及病理性质对3D-SWE图像质量的影响。结果 图像质量1级105例（105/187，56.15%），2级59例（59/187，31.55%），3级23例（23/187，12.30%）。操作中有无附加压力、病变位置、病理性质、病变最大径、病变深面距离皮肤最长垂直距离及病变前方脂肪层最厚厚度均为3D-SWE图像质量的影响因素（P均<0.05）。结论 操作有无附加压力、病变位置、大小、深度及病理性质可影响3D-SWE图像质量。 |

| Objective To explore the impact factors of imaging quality of three-dimensional shear wave elastography (3D-SWE) for focal breast lesions. Methods A total of 187 patients with focal breast lesions underwent 3D-SWE examination, and the imaging quality was classified into three grades, including Grade 1 (good), Grade 2 (common) and Grade 3 (poor). The impact of additional operating pressure, breast type, coupling agent thickness, and the location, size, depth as well as pathology of lesions on imaging quality were analyzed. Results Grade 1 images were found in 105 (105/187, 56.15%) patients, Grade 2 images were observed in 59 (59/187, 31.55%) patients, while Grade 3 images were noticed in 23 (23/187, 12.30%) patients. Additional operating pressure, location, pathology, the maximum diameter of lesions, the largest vertical distance from deep side of the lesion to skin and the thickest fat layer in front of the lesion were the impact factors of 3D-SWE imaging quality (all P<0.05). Conclusion The imaging quality of 3D-SWE is influenced by the additional operating pressure and the location, size, depth and pathology of lesions. |
