摘　　要：目的测量乳腺肿块同一部位在改变探头放置方向时的剪切波传播速度并评价测值的差异。方法对48例女性患者（92个乳腺肿块）进行剪切波成像超声检查，测量肿块中心在横切、斜切、纵切面上的剪切波传播速度，收集病检结果。结果病理诊断均为良性乳腺病变。乳腺肿块在三个切面中最小与最大剪切波传播速度差异有统计学意义（P〈0．001）。结论改变探头放置方向时乳腺肿块的剪切波传播速度有差异，故应用剪切波传播速度对乳腺肿块进行鉴别诊断需考虑此差异的影响。Objective To obtain the shear wave velocity（SWV） in breast tumors at different probe orientations. Methods SWV was measured on 92 breast tumors in 48 female patients with the probe placed on transverse, longitudinal and 45 degree planes. Pathological test results were followed up. Results Pathological tests showed benign tumors in 48 patients （92 tumors）. Of the three planes, values of the biggest and the smallest SWV showed significant difference （ P 〈0. 001）. Conclusions SWV differs on different planes of breast tumors. So the effect in different probe orientations should be considered using SWV for the differential diagnosis of breast tumors. [
