超声 MicroPure 成像对 BI-RADS 4级的乳腺肿块微钙化检出的价值

目的：评价应用超声 MicroPure 成像技术对 BI-RADS分级为4级的乳腺肿块中微钙化的检测价值。方法对56例发现乳腺肿块并且 BI-RADS 分级为4级的患者分别应用X 线钼靶、传统灰阶超声及 MicroPure 成像技术进行肿块微钙化的检测，以钼靶为金标准，对传统灰阶超声和 MicroPure检测结果进行比较。同时结合术后病理结果进行分析。结果56例乳腺肿块中，钼靶发现43个病灶有微钙化，传统灰阶超声发现其中22个病灶有微钙化，MicroPure 成像技术发现40个病灶有微钙化。传统灰阶超声检测病灶内部及周边微钙化的敏感性为51．2％，特异性为92．3％，ROC 曲线下面积为0．717；MicroPure 成像技术检测病灶内部及周边微钙化的敏感性为93．0％，特异性为100．0％，ROC 曲线下面积为0．965。结论在 BI-RADS 分级为4级的乳腺肿块微钙化的检测中，超声 MicroPure 成像技术明显优于传统灰阶超声，有助于乳腺癌的临床诊断。

Value of using MicroPure imaging technology for the detection of microcalcifications in BI-RADS 4 breast lumps

Objective To evaluate the diagnostic value of MicroPure imaging technology for the detection of micro-calcifications screening in BI-RADS 4 patients with breast lumps.Methods 56 women with breast lumps classified as BI-RADS 4 patients underwent X-ray mammographytraditional,gray-scale ultrasound and MicroPure imaging technology for microcalcifications detection.With mammography results as the gold standard,the results of tradi-tional ultrasound were compared with those of MicroPure imaging technology,then those were analyzed combined with postperative pathological results.Results In 56 cases,microcalcifications were found in 43 lumps with mam-mography,22 lumps with traditional ultrasound,and 40 lumps with MicroPure imaging technology.To detect mi-crocalcifications within and around of masses,the sensitivity and specificity were 51.2% and 92.3% for traditional ultrasound,the area under the ROC curve was 0.717,then the sensitivity and specificity were 93.0% and 100.0% for MicroPure imaging technique,the area under the ROC curve was 0.965.Conclusion In the BI-RADS 4 lumps of microcalcification detection,MicroPure imaging technology is obviously superior to traditional ul-trasound,then it can help in the clinical diagnosis of breast cancer.
