摘要

目的：

评价声脉冲辐射力成像(acoustic radiation force impulse imaging，ARFI)技术中3个主要诊断参数面积比(area ratio，AR)、应变率(strain ratio，SR)和剪切波速度(shear wave velocity，SWV)单独诊断及联合诊断在临床鉴别乳腺肿块良恶性中的意义。

方法：

对113例患者132个实性乳腺肿块的ARFI特征进行分析，回归分析3个诊断指标，拟合出联合诊断方法预测概率的新变量PRE-1。以病理结果为金标准，用受试者工作特征(receiver operating characteristic，ROC)曲线对3个参数单独诊断及联合诊断的效能进行评估。

结果：

132个乳腺肿块的病理诊断结果显示，良性肿块69个，恶性肿块63个。良性病灶的AR、SR、SWV值分别为2.821.03、1.260.40、(3.100.99) m/s，均低于恶性组的4.321.58、2.090.91、(5.051.65) m/s，差异有统计学意义(

＜0.05)。AR、SR、SWV值ROC曲线的曲线下面积分别为0.812、0.807和0.843，3个参数联合诊断ROC曲线的曲线下面积为0.954。

结论：

3个参数联合诊断乳腺肿块良恶性的效能最好，从而为临床诊断乳腺肿块良恶性提供了更多的参考方法。

Abstract

Objective:

To study the application value of alone or combination of three main elastic parameters-area ratio (AR)

strain ratio (SR) and shear wave velocity (SWV) of acoustic radiation force impulse imaging (ARFI)-in the identification of breast tumors.

Methods:

The characteristics of 132 breast masses in 113 cases were analyzed using ARFI. A regression equation was established

and a new variable PRE-1 to predict the probabilit

y was obtained by regression analysis of the three diagnostic indicators. The pathological results were set as the reference

and the diagnostic performance of three parameters alone and combined was evaluated using receiver operating characteristic (ROC) curves.

Results:

In total 132 lesions of 113 patients

69 lesions were benign and 63 were malignant. Benign tumors had an average AR of 2.821.03

SR of 1.260.40

which were significantly lower than malignant tumors (4.321.58 and 2.090.91

respectively)(

0.05); transverse SWV of the benign lesions was (3.100.99) m/s

which was significantly lower than that of the malignant lesions [(5.051.64) m/s

]

(

0.05). The areas under the ROC curves of AR

SWV were 0.812

0.807

0.843

respectively

and 0.954 for combined diagnosis.

Conclusion:

The combined diagnosis of three parameters in the identification of benign or malignant breast masses is valuable. It provides more ideas and methods in the clinical diagnosis of breast masses.
