超声弹性成像对乳腺小实性病灶的鉴别诊断价值

目的 探讨超声弹性成像在乳腺小实性病灶(最大径≤10mm)鉴别诊断中的价值.方法 回顾性分析经手术病理证实的274个乳腺小实性病灶的常规超声及超声弹性成像图像.常规超声采用BI-RADS-US标准判断病灶的良恶性.超声弹性成像采用改良5分评分法判断病灶的良恶性.以手术病理结果为诊断金标准,构建受试者工作特征曲线,比较两种方法对乳腺肿物的诊断率.结果 超声弹性成像及常规超声BI-RADS分级诊断乳腺良恶性病灶的曲线下面积分别为0.891和0.742,差异有统计学意义(Z=4.053,P＜0.001).结论 超声弹性成像有助于乳腺小实性病灶的鉴别诊断.

Value of ultrasonic elastography in diagnosing breast small masses

Objective To investigate the value of ultrasonic elastography(UE) in diagnosing breast small masses (diameter≤10 mm). Methods The static sonograms of conventional ultrasound(US) and UE of the 274 breast small lesions which pathologically proved were reviewed. Images were assigned according to the B1-RADS criteria for US. The elastographic images were evaluated using improved 5-scoring system.Pathology was followed up as diagnostic criteria. The diagnostic performance of the 2 methods was evaluated with receiver operating characteristic curve(ROC). Results The areas under the ROC curve of the two modalities were 0. 891 (UE) and 0.742 (BI-RADS), respectively. The difference between them was significant. Conclusions UE is helpful in differentiating between malignant and benign breast small lesions.
