【摘要】：目的:探討在不同切面中應(yīng)用超聲彈性成像面積比值法對BI-RADS 4級乳腺腫塊良惡性判斷的價值。方法:對97例患者共116個BI-RADS 4級乳腺腫塊分別進行腫塊橫徑最大切面(A切面)、縱橫比最大切面(B切面)、感興趣部位最大面積切面(C切面)彈性成像檢查,對彈性成像圖像進行面積比值法分析。以病理診斷為金標準,繪制受試者工作特征曲線,判斷三個不同切面對BI-RADS 4級乳腺腫塊的診斷價值。結(jié)果:A、B、C三個切面BI-RADS 4級乳腺腫塊良、惡性組間面積比值差異均具有統(tǒng)計學(xué)意義。三個切面所構(gòu)建ROC曲線間比較差異無統(tǒng)計學(xué)意義。A切面面積比值以1.33為臨界點判斷腫塊良惡性的敏感性、特異性、準確性分別為75.8%、95.2%、89.7%;B切面面積比值以1.25為臨界點判斷腫塊良惡性的敏感性、特異性、準確性分別為84.8%、85.5%、85.3%;C切面面積比值以1.55為臨界點判斷腫塊良惡性的敏感性、特異性、準確性分別為81.8%、95.2%、91.4%。結(jié)論:A、B、C三個不同切面超聲彈性成像面積比值均有助于提高BI-RADS 4級乳腺腫塊良惡性鑒別診斷。
[Abstract]:Objective: to evaluate the value of ultrasound elastic imaging area ratio method in the diagnosis of benign and malignant breast masses in BI-RADS grade 4 in different sections. Methods: a total of 116 BI-RADS grade 4 breast masses in 97 patients were examined by elastic imaging with maximum transverse diameter (A section), maximum aspect of aspect ratio (B section) and maximum area of interest (C section). The area ratio method was used to analyze the elastic imaging images. According to the gold standard of pathological diagnosis, the operating characteristic curve of the subjects was drawn to judge the diagnostic value of three different cuts to the BI-RADS grade 4 breast masses. Results there were significant differences in the area ratio among the three BI-RADS grade BI-RADS grade 4 breast masses. There was no significant difference between the ROC curves constructed by the three sections. The ratio of the area of section to the section area was 1.33 as the critical point to judge the sensitivity and specificity of benign and malignant tumors. The sensitivity, specificity and accuracy of 84.8and 85.3C section area ratio of 85.3C to 1.55 were used to judge the sensitivity, specificity and accuracy of the tumor, respectively. The sensitivity, specificity and accuracy were 81.8% and 95.21.4%, respectively, according to the critical point of 1.55. Conclusion the area ratio of ultrasound elastic imaging on three different sections is helpful to improve the differential diagnosis of benign and malignant breast masses in grade 4 of BI-RADS.
