US elastography is an emerging technique that can be used during breast US examination. The increasing awareness of breast cancer led to an increase in mammography and breast US examinations. The specificity of these techniques is not high enough to prevent unnecessary biopsies. There is still a need for a more specific technique that can overcome this problem. This study aimed to evaluate the value of strain elastography in breast lesions.
In this study, 110 lesions of 96 patients were evaluated with strain elastography. Five score system was used for lesion scoring. The histopathologic results of lesions were obtained and were accepted as gold standard. The sensitivity, specificity, PPV and NPV of the technique were calculated. Histopathologic and strain elastography results were correlated.
The sensitivity of US strain elastography was calculated as 83%, the specificity as 89%, the positive predictive value as 79% and the negative predictive value as 91%. There were no score 1 lesions. All score 2 lesions were benign. Score 5 had the highest true positivity rate.
We believe that ultrasound elastography is an effective imaging technique that can be used as an adjunct for differential diagnosis, prior to the decision to biopsy a lesion in certain cases.
美国弹性成像技术是一种新兴技术，可用于乳腺超声检查。乳腺癌意识的提高导致乳腺钼靶和乳腺超声检查的增加。这些技术的特异性不足以防止不必要的活检。仍然需要一种更具特异性的技术来克服这个问题。本研究旨在评估应变弹性成像在乳腺病变中的价值。
在本研究中，对96例患者的110个病变进行了应变弹性成像评估。采用五分制对病变进行评分。获取病变的组织病理学结果并将其作为金标准。计算该技术的敏感性、特异性、阳性预测值和阴性预测值。将组织病理学结果与应变弹性成像结果进行相关性分析。
超声应变弹性成像的敏感性计算为83%，特异性为89%，阳性预测值为79%，阴性预测值为91%。没有1分的病变。所有2分的病变均为良性。5分的真阳性率最高。
我们认为，超声弹性成像是一种有效的成像技术，在某些情况下决定对病变进行活检之前，可作为鉴别诊断的辅助手段。
