目的:探讨女性钼靶乳腺影像学报告与数据系统(BI-RADS)Ⅳ级乳腺小肿块的超声诊断价值,为乳腺癌的早期诊断提供理伦依据。方法:选取2011年11月~2012年3月在该院进行钼靶筛查并诊断为存在高度可疑恶性BI-RADSⅣ级乳腺小肿块的患者89例。所有患者均进行乳腺超声检查及开放手术活检或真空组织活检,分析患者的超声图像和超声分级结果特征。结果:超声检查老年女性钼靶BI-RADSⅣ级乳腺小肿块敏感性、特异性及准确性均较高。恶性肿块具有病灶形状不规则、边界模糊、纵长大于横长,病灶内部有钙化灶及血流等超声特点。结论:对于老年女性患者,钼靶评估筛查能够为BIRADSⅣ级乳腺小肿块病灶的初步诊断提供依据,同时针对超声检查阴性的患者可以进行短期随访,减少活检比例。
OBJECTIVE: To investigate the value of ultrasonography in the diagnosis of grade IV breast mass in mammography and data system (BI-RADS), and provide the basis for the early diagnosis of breast cancer. Methods: From November 2011 to March 2012, 89 patients with molybdenum target screening and diagnosis of highly suspicious malignant BI-RADS grade IV breast mass were selected. All patients underwent ultrasonography of the breast and open surgery biopsy or vacuum tissue biopsy to analyze the characteristics of the patient’s ultrasound images and ultrasound grading results. Results: The sensitivity, specificity and accuracy of ultrasonography in detecting small breast tumors of males with BI-RADS Ⅳ grade were higher. Malignant lesions with irregular shape, fuzzy boundaries, length longer than horizontal length, lesions within the calcification and blood flow and other ultrasonic characteristics. Conclusion: In elderly female patients, mammography screening can provide a basis for the primary diagnosis of small breast lesions in BIRADS class Ⅳ, and short-term follow-up of patients with negative ultrasound can reduce the proportion of biopsy.
