超声BI-RADS分级与传统方式对于NLM诊断价值的比较分析

Comparison between the value of ultrasound BI-RADS classification and traditional way in diagnosis of NLM

目的 比较乳腺超声BI-RADS分级与传统未分级方式对于非哺乳期乳腺炎（NLM）的诊断价值。方法 选择2014年1月~2015年5月临床诊断为NLM的患者90例,分别采用超声BI-RADS分级的方式及传统未分级的方式进行超声诊断。所有患者均通过空芯针穿刺活检获得病理组织学诊断,以术后病理诊断为“金标准”,分别计算超声BI-RADS分级与传统未分级超声诊断结果的阳性预测值、阴性预测值、灵敏度与特异度。结果 超声传统未分级的方式诊断NLM的灵敏度为96%,特异度为78%,阳性预测值为97%,阴性预测值为70%,均高于超声BI-RADS分级方式（灵敏度23%,特异度为67%,阳性预测值86%,阴性预测值10%）（P〈0.01）。结论 传统未分级方式对于NLM诊断的灵敏度、特异度、阳性预测值、阴性预测值更高,更具有诊断价值。

Objective To make comparison between the value of breast ultrasound BI-RADS classification and the traditional way in the diagnosis of unrated non-lactating mastitis （NLM）. Methods 90 cases clinically diagnosed as NLM between January 2014 and May 2015 were selected and received the ultrasonic diagnosis by ultrasound BI-RADS classification and traditional manner of unrated way, respectively. All the patients obtained the histopathologic diagnosis through core needle biopsy. Setting the postoperative pathologic diagnosis as ＂gold standard＂, calculation was made in the positive and negative predictive values, sensitivity, and specificity of the results diagnosed by ultrasound BI-RADS classification method and unrated conventional way. Results The sensitivity, specificity, positive and negative predictive values unrated conventional way for the diagnosis of NLM was 96%, 78%, 97%, 70%, respectively, which was higher than those of the ultrasound BI-RADS classification method （sensitivity 23%, specificity 67%, positive and negative predictive values 86% and 10%）（P 〈 0.01）. Conclusion The traditional unrated way for the diagnosis of NLM has higher sensitivity, specificity, positive and negative predictive values and more diagnostic value.
