乳腺肿块术前超声诊断的评价

Evaluation of preoperative ultrasonographic diagnosis in breast neoplasm

目的评价超声检查对乳腺肿块诊断的临床应用价值。方法对经手术病理证实的137例乳腺肿块与超声结果进行了回顾性对比分析。结果良、恶性肿块均以低回声型为主要图像表现;良、恶性两组间在形态、边界、包膜、后方回声、微小钙化斑检出率、血流检出率比较,差异均有统计学意义(P<0.05)。腋窝转移性淋巴结以淋巴结肿大,内部低回声为声像图特征。结论以二维超声为基础,结合彩色多普勒血流显像以及腋窝淋巴结检查,可提高乳腺肿块的术前诊断符合率。

Objective To evaluate the clinical application of ultrasound diagnosis for breast neoplasm.Methods The ultrasound examination in 137 cases with pathologically proved breast neoplasm was done and the clinical data were retrospectively analyzed.Results The main sonogram of breast neoplasm showed hypoechoic masses.The benign and malignant breast tumors were significantly different in shape,boundary,capsules,rear echo,detection rates of minute calcification and blood flow display rates（P〈0.05）.The ultrasonographic characteristics of axillary metastatic lymph node were enlarged and low internal-echo.Conclusions The preoperative diagnosis rate of breast neoplasm can be improved by color Doppler flow imaging on the basis of two dimensional ultrasonography combined with axillary lymph node examination.
