目的:探究高频超声在乳腺微小结节良恶性鉴别诊断中的应用价值及其超声表现。方法:选取我院乳腺外科收治的确诊为乳腺微小结节的患者184例,术前采用高频超声技术对患者进行结节探测,将探测结果与病理切片比较,同时对良恶性微小结节之间的形态、血流、微钙化以及边缘轮廓等情况进行图像分析,总结两者之间存在的差异。结果:1经过高频超声,检测出184例乳腺微小结节患者,有238处微小结节,其中良性结节194处、恶性结节44处;病理切片显示,微小结节244处,其中良性结节197处、恶性结节47处。与病理切片比较,高频超声的结节检出率高达97.5%,良恶性结节的检出准确率分别为98.5%、93.6%;2结节形态规则度对比,良性结节较恶性结节更规则(P<0.05);钙化情况比较,并非所有结节都出现钙化,两者钙化情况暂无可比性;结节边缘轮廓清晰度比较,良性结节多表现为边缘清晰,而恶性肿瘤多表现为边缘模糊;结节边缘良性结节较恶性结节更清晰;3血流检出率比较,恶性结节组显著高于良性结节组(P<0.05)。结论:高频超声技术对乳腺微小结节的检出率较高,错误率较低,是鉴别乳腺微小结节良恶性的重要手段,具有较高的应用价值,对乳腺癌的早期诊断具有重大意义。
Objective: To investigate the value of ultrasonography in the differential diagnosis of benign and malignant breast microtumor nodules. Methods: A total of 184 patients with minimal breast nodules diagnosed by breast surgery in our hospital were selected. The nodules were detected by high-frequency ultrasonography before surgery. The results of the detection were compared with those of pathological sections. Between the morphology, blood flow, micro-calcification and the edge of the contour image analysis, summed up the differences between the two. Results: 1 After ultrasonography, 184 cases of minimally invasive breast nodules were detected, with 238 tiny nodules, including 194 benign nodules and 44 malignant nodules. The pathological sections showed that there were 244 tiny nodules, of which benign 197 nodules, 47 malignant nodules. Compared with pathological sections, the detection rate of high-frequency ultrasound nodules was as high as 97.5%, and the detection accuracy of benign and malignant nodules were 98.5% and 93.6% respectively. 2 Comparison of nodular morphology regularity, benign nodules more malignant nodules More regular (P <0.05); calcification, not all calcifications appear calcification, the two calcifications are not comparable; nodular edge contour clarity, benign nodules more performance for the edge of the clear, and more malignant tumors Showed edge fuzzy; nodular benign nodules more clearly than malignant nodules; 3 blood flow detection rate was significantly higher in malignant nodules than in benign nodules (P <0.05). Conclusion: The high frequency ultrasound technique has a high detection rate and a low error rate in the diagnosis of small breast nodules, which is an important method to distinguish benign and malignant breast nodules. It has high application value and is of great importance in the early diagnosis of breast cancer significance.
