摘要

目的：

探讨剪切波弹性成像（shear wave elastography，SWE）联合超微血管显像（super microvascular imaging， SMI）在乳腺病灶良恶性鉴别诊断中的应用价值。

方法：

对236例乳腺占位性病变患者共272个病灶进行SWE及SMI检查。以手术后病理学检查结果为金标准，评价SWE、SMI及两者联合对乳腺病灶良恶性的鉴别诊断效能，并应用受试者工作特征（receiver operating characteristic，ROC）曲线分析SWE的最大值（E

max

）、平均值（E

mean

）、最小值（E min ）、标准差（SD）以及病灶与周边正常组织比值（E ratio ）对乳腺病灶良恶性的鉴别诊断价值。

结果：

272个病灶中，良性病灶125个，恶性病灶147个。恶性病灶的E

Abstract

Objective:

To investigate the application value of shear wave elastography (SWE) combined with superb microvascular imaging (SMI) in differential diagnosis of benign and malignant breast lesions.

Methods:

SWE and SMI examinations were performed on 272 lesions in 236 patients with breast lesions. The diagnostic efficacy of SWE

SMI and their combination in differentiating benign from malignant breast lesions were evaluated based on the results of surgical pathology. The value of the maximum (E

max

)

average (E

)

minimum (E

)

standard deviation (SD) of SWE and the ratio of lesions to peripheral normal tissues (E

ratio

) in the differential diagnosis of benign and malignant breast lesions was analyzed by receiver operating characteristic (ROC) curve.

Results:

Among the 272 lesions

125 were benign and 147 were malignant. E

SD［(24.713.5) kPa

(3.42.0) kPa］ and E

ratio

(5.72.2

1.40.5) in malignant lesions were significantly higher than those in benign lesions (

＜0.01). There were more cases of the Alder blood flow Ⅱ-Ⅲ grade in malignant lesions than that in benign lesions (

＜0.01). The sensitivity

specificity and accuracy of SWE combined with SMI in differentiating benign and malignant breast lesions were 97.3%

94.4% and 96.0%

respectively. The area under curve (AUC) of E

SD and E

ratio

in differentiating benign and malignant breast lesions were 0.938

0.882

0.806

0.870 and 0.904

respectively. When E

max

was 76.8 kPa

the sensitivity and specificity of differentiating benign from malignant breast lesions were 93.5% and 91.8%

respectively.

Conclusion:

max

has highervalue in differential diagnosis of benign and malignant breast lesions

and SWE combined with SMI can improve the accuracy of differential diagnosis.
