目的:评价非触摸性乳腺疾病(NPBLs)超声诊断分级的应用。方法:选取158例临床触诊阴性并接受超声体表定位患者的影像学资料,采用欧洲分级系统进行分级,并与切取活检后的病理结果进行比较。结果:158例患者病理确诊为良性124例,恶性34例。病理确诊为乳腺癌的34例患者中,超声诊断为正常/良性的3例(8.8%),交界性病变2例(5.9%),可疑/符合恶性29例(85.3%),乳腺X线诊断为正常/良性12例(35.3%),交界性9例(26.5%),可疑/符合恶性13例(38.2%)。超声的敏感性显著高于乳腺X线的敏感性(94.1%vs38.2%,P=0.000)。超声诊断的特异性和乳腺X线差异无统计学意义(96.0%vs91.1%,P=0.118)。结论:对于NPBLs的影像学诊断,超声起到较好的诊断作用。
OBJECTIVE: To evaluate the application of ultrasonic diagnostic grading of non-touch breast diseases (NPBLs). Methods: The imaging data of 158 patients who were negative in clinical palpation and underwent ultrasonography were selected. The data were graded using the European grading system and compared with the biopsy results. Results: 158 cases of pathological diagnosis of benign 124 cases, 34 cases of malignant. Of the 34 patients with pathologically diagnosed breast cancer, 3 (8.8%) were diagnosed as normal / benign by ultrasound, 2 were borderline (5.9%), 29 were suspicious / malignant (85.3%), 12 cases (35.3%) were normal / benign, 9 cases (26.5%) were borderline, and 13 cases (38.2%) were suspicious / malignant. The sensitivity of ultrasound was significantly higher than that of mammography (94.1% vs 38.2%, P = 0.000). There was no significant difference in the specificity of ultrasound diagnosis and mammography (96.0% vs 91.1%, P = 0.118). Conclusion: For the imaging diagnosis of NPBLs, ultrasound plays a good diagnostic role.
