【摘要】：目的探討Vibrant動(dòng)態(tài)增強(qiáng)聯(lián)合MR血管成像在乳腺良惡性病變?cè)\斷中應(yīng)用價(jià)值。方法 36例患者共40個(gè)病灶,其中惡性病灶18個(gè),良性病灶22個(gè),行乳腺動(dòng)態(tài)增強(qiáng)MRI檢查,并重建得到3D-MIP圖像。在GE ADW 4.3圖像工作站運(yùn)用Functool功能軟件對(duì)增強(qiáng)病變進(jìn)行血流動(dòng)力學(xué)分析。結(jié)果以Ⅱ~Ⅲ型曲線,信號(hào)增強(qiáng)率90%,峰值時(shí)間出現(xiàn)在3 min之前,周圍血管征陽(yáng)性作為惡性標(biāo)準(zhǔn),敏感性分別為88.9%、88.9%、83.3%、77.8%,特異性分別為72.7%、54.5%、90.9%、86.4%,準(zhǔn)確性分別為80%、70%、87.5%、82.5%,陽(yáng)性預(yù)測(cè)值分別為72.7%、61.5%、88,2%、82.4%,陰性預(yù)測(cè)值分別為88.9%、85.7%、86.9%、82.6%,良惡性差異有統(tǒng)計(jì)學(xué)意義(P0.05)。結(jié)論 Vibrant動(dòng)態(tài)增強(qiáng)血流動(dòng)力學(xué)特征聯(lián)合周圍血管征在乳腺良惡性病變判斷方面具有重要價(jià)值。
[Abstract]:Objective to evaluate the value of dynamic contrast-enhanced Vibrant combined with MR angiography in the diagnosis of benign and malignant breast lesions. Methods Thirty-six patients with 40 lesions, including 18 malignant lesions and 22 benign lesions, were examined by dynamic contrast-enhanced MRI. 3D-MIP images were obtained by reconstruction. The hemodynamic analysis of enhanced lesions was performed on GE ADW 4.3 image workstation with Functool software. Results according to the type 鈪，
