| 目的 探讨超声BI-RADS分类对不同超声分型乳腺内结节的诊断价值。
方法 通过检索本院电子病历系统，获取2014年6月至2016年4月间，在我院因乳腺结节住院且行手术的病历资料，选取其中术前乳腺超声检查资料齐全、超声BI-RADS分类及术后病理结果明确的病历305例，年龄16-76岁，平均56±18岁。按照乳腺组织大体的声像图特点，将乳腺分为腺体型、腺纤维Ⅰ型、腺纤维Ⅱ型及脂肪型。乳腺结节的超声BI-RADS分类参照美国放射学院指南。以手术病理结果为金标准，病理结果采用良、恶性二分类法，分别计数各型乳腺内结节的BI-RADS分类，数据采用SPSS19.0进行ROC曲线分析。
结果 本组病例乳腺内结节超声BI-RADS分类的ROC曲线下面积为0.963，不同超声类型乳腺内结节超声BI-RADS分类的ROC曲线下面积分别为：0.933（腺体型），0.902（腺纤维Ⅰ型），0.953（腺纤维Ⅱ型），0.989（脂肪型）；超声BI-RADS分类区别各型乳腺内结节良、恶性的截断点均为4b-4c。
结论 超声BI-RADS分类对不同超声分型乳腺内结节均有良好的诊断效度，且对不同类型乳腺内结节良、恶性鉴别的最佳截断点亦一致。 |

| Abstract: |
| Objectives Aimed to evaluate the value of ultrasound BI-RADS category on breast nodules of different breast ultrasound types.
Methods Through searching the electronic medical record system for hospitalization and surgery for breast nodules in our hospital from June 2014 to April 2016, three hundred and five cases were selected for analysis with complete preoperative ultrasonography data, clear ultrasound BI-RADS category and postoperative pathological results. These patients were 16 to 76 years old, with average age of 56±18 years old. According to the whole sonographic features of breast tissue, the breasts were divided into glandular type, gland fiber typeⅠ, gland fiber type Ⅱand fat type. Ultrasound BI-RADS category on breast nodules followed the American College of Radiology guidelines. The pathology results were as the gold standard, which were classified into benign and malignant. The number of various BI-RADS category of the breast nodules were counted in different ultrasound types and the data were analyzed by SPSS19.0 for ROC analysis.
Results Area under the ROC curve of BI-RADS category was 0.963 in a whole. Area under the ROC curve of BI-RADS category on nodules in different breast ultrasound types was as follows respectively: 0.933 (glandular type), 0.902 (gland fiber type I), 0.953 (gland fiber type II), and 0.989 (fat type). The benign and malignant cutoff points were between 4b and 4c of ultrasound BI-RADS category in different breast ultrasound types.
Conclusions Ultrasound BI-RADS category had good diagnosing validity on breast nodules in different breast ultrasound types, and the best cut-off points of ultrasound BI-RADS category were consistent in different ultrasound types of breast. |
