This study aimed to investigate the effect of calcifications on shear-wave elastography in evaluating breast lesions. We retrospectively reviewed ultrasound images of 673 breast lesions and compared the elasticity between lesions with and without calcifications in three subgroups: benign lesions, in situ carcinomas and invasive carcinomas. Breast lesions were confirmed histologically (n = 401) or by follow-up images for more than 2 y (n = 272). Calcifications were present in 25.3% (170/673) of the lesions. The E values with and without calcifications, respectively, were as follows: 62.8 and 29.8 kPa in benign lesions (p = 0.000), 114.6 and 52.8 kPa in in situ carcinomas (p = 0.037) and 171.9 and 146.4 kPa in invasive carcinomas (p = 0.018). The presence of calcifications significantly increased the E of breast lesions. Shear-wave elastography should be carefully interpreted in benign lesions with calcifications and in situ carcinomas without calcifications.
本研究旨在探讨钙化对评估乳腺病变的剪切波弹性成像的影响。我们回顾性分析了 673 例乳腺病变的超声图像，并在三个亚组（良性病变、原位癌和浸润性癌）中比较了有钙化和无钙化的病变之间的弹性。乳腺病变通过组织学（n=401）或 2 年以上的随访图像（n=272）证实。673 例病变中有 25.3%（170/673）存在钙化。有钙化和无钙化的 E 值分别为：良性病变分别为 62.8kPa 和 29.8kPa（p=0.000），原位癌分别为 114.6kPa 和 52.8kPa（p=0.037），浸润性癌分别为 171.9kPa 和 146.4kPa（p=0.018）。钙化的存在显著增加了乳腺病变的 E 值。在有钙化的良性病变和无钙化的原位癌中，剪切波弹性成像的结果应谨慎解释。
