摘要
目的:探讨超声学检查在乳腺肿块鉴别诊断中的应用价值。方法:选择单发乳腺肿块患者109例,所有患者术前均于我院行超声学检查,术后均行病理学检查明确肿块性质。以病理学结果为标准,观察超声对乳腺良、恶性肿块的诊断符合率。比较良、恶性乳腺肿块的超声学特征及血流特点。结果:①超声对良、恶性肿块的诊断符合率分别为94.9%和93.5%。②恶性乳腺肿块形态不规则、边缘不清晰、包膜不完整、内部回声不均匀、纵横比≥1、后方回声衰减、伴有对周围组织侵润及腋窝淋巴结肿大的比例均明显高于良性乳腺肿块(P<0.01)。③恶性乳腺肿块平均动脉收缩期峰值流速(PSV)约为(20.8±3.9)cm/s,阻力指数(RI)均值约为0.9±0.3,均明显高于良性乳腺肿块(P<0.05)。结论:超声学检查诊断准确率高,在乳腺肿块的鉴别诊断中有重要的意义。
Objective： To study the application value of ultrasound in differential diagnosis of breast mass.Method： 109 cases with single breast mass were chosen,all patients underwent preoperative ultrasound examination,and were confirmed by pathological examination.The diagnosis rate of benign and malignant tumor,ultrasound characteristics,blood flow characteristics of the mass were observed.Result： ①the diagnosis rate of benign and malignant tumor were 94.9% and 93.5%.②In malignant breast tumors,the rate of irregular,the edge is not clear,incomplete capsule,heterogeneous internal echo,aspect ratio≥1,posterior echo attenuation,with invasion of surrounding tissue and axillary lymph nodes were significantly higher than those of benign breast tumor（P0.01）.③The PSV and RI of the malignant breast tumors were（20.8 ± 3.9）cm/s and 0.9±0.3,significantly higher than those of benign breast tumors（P0.05）.Conclusion： Ultrasound examination has high accuracy,it is important in the differential diagnosis of breast mass.
