【摘要】：目的探討三陰性乳腺癌(TNBC)的鉬靶X線及MRI影像學(xué)表現(xiàn)特征。方法搜集經(jīng)病理及免疫組織化學(xué)證實(shí)的57例TNBC,其中44例行鉬靶X線攝影,7例行MR平掃及增強(qiáng),6例行鉬靶X線攝影及MRI檢查。回顧性分析其鉬靶X線及MRI表現(xiàn),測(cè)量病灶的表觀擴(kuò)散系數(shù)(ADC)值,記錄腫塊動(dòng)態(tài)增強(qiáng)的時(shí)間-信號(hào)強(qiáng)度曲線(TIC)類型。結(jié)果鉬靶X線攝影在50例檢查者中42例發(fā)現(xiàn)病灶,單純腫塊27例,腫塊伴鈣化11例,單純鈣化4例;腫塊多呈類圓形或卵圓形,28例腫塊邊緣清楚、光滑。MRI上11例為單一腫塊,2例為非腫塊型,病灶在T1WI上呈低或中等信號(hào),在T2WI上2例腫塊較小者呈高信號(hào),11例呈等高混雜信號(hào);11例腫塊型中,邊緣光滑4例,5例均勻強(qiáng)化,3例呈環(huán)形強(qiáng)化,3例不均勻強(qiáng)化;平均ADC值為1.2×10-3mm2/s,8例TIC呈Ⅲ型。結(jié)論 TNBC的鉬靶X線及MRI表現(xiàn)有一定特征性,提高對(duì)特征性表現(xiàn)的認(rèn)識(shí)有助于術(shù)前作出正確診斷。
[Abstract]:Objective to investigate the features of mammography and MRI in tri-negative breast cancer. Methods 57 cases of TNBC confirmed by pathology and immunohistochemistry were collected. Among them, 44 cases were treated with mammography, 7 cases with Mr plain scan, 6 cases with enhanced Mr and 6 cases with MRI. The X-ray and MRI findings of the lesions were analyzed retrospectively. The apparent diffusion coefficient (ADCC) of the lesions was measured and the time-signal intensity curves of dynamic enhancement were recorded. Results Molybdenum target radiography found lesions in 42 out of 50 patients, 27 with simple mass, 11 with calcification and 4 with simple calcification. Smooth. MRI showed that 11 cases were single mass and 2 cases were non-mass type. The lesions showed low or medium signal intensity on T1WI, while on T2WI 2 cases showed high signal intensity and 11 cases showed iso-high mixed signal intensity in 11 cases. There were 4 cases with smooth edges and 5 cases with homogeneous enhancement. The average ADC value was 1.2 脳 10 ~ (-3) mm ~ (-2) / s ~ (-1) and TIC was type 鈪，
