小乳腺癌的声像图与穿刺活检诊断价值分析

目的分析乳腺小肿块临床特点、彩超声像图特征及高频超声下定位穿刺活检,提高诊断早期乳腺病变的准确率。方法通过研究乳腺小肿块84例(乳腺癌44例,良性肿瘤40例),怀疑恶性的24例乳腺肿块进行超声下定位穿刺活检,全部病例均经手术和病理证实。先用二维超声观察肿块的数量、边界、大小、内部回声、后方及侧壁回声、有无钙化、纵横比。然后在高频彩超下观察周边及病变内部的血流情况,并测量血流动力学参数。结果高频彩超与超声下定位穿刺活检联合应用,恶性肿块的诊断特异性为93.8%、准确性为92.3%,敏感性为90.8%。结论联合应用高频彩超与高频超声下定位穿刺活检,对于诊断和鉴别诊断乳腺小肿块,可明显提高诊断乳腺病变的准确率。

Ultrasound and biopsy diagnosis of the clinical value of small breast lumps

Objective Analysis of sonographic features of early breast cancer,clinical features and ultrasound guided biopsy improve the early diagnosis of breast cancer.Methods Studied 84 patients with small breast tumors（40 cases were benign tumors,44 cases of breast cancer）,malignant in 24 cases of suspicious breast mass ultrasound guided biopsy,all cases were confirmed by pathology and surgery.The first two-dimensional ultrasound tumor size,number,boundaries,aspect ratio,internal echo,with or without calcification,and the rear wall echo.Then in color Doppler flow imaging of tumor blood flow within and around the measured hemodynamic parameters.Results High-frequency ultrasound and ultrasound guided biopsy in combination,the diagnosis of malignant lesions was 90.8% sensitivity and specificity of 93.8%,accuracy 92.3%.Conclusion Attention to signs of early cancer,combined with color Doppler ultrasonography and ultrasound guided biopsy and axillary lymph nodes combined with ultrasound breast mass ultrasound can improve diagnostic accuracy.
