【摘要】：目的探讨三阴性乳腺癌(TNBC)的钼靶X线及MRI影像学表现特征。方法搜集经病理及免疫组织化学证实的57例TNBC,其中44例行钼靶X线摄影,7例行MR平扫及增强,6例行钼靶X线摄影及MRI检查。回顾性分析其钼靶X线及MRI表现,测量病灶的表观扩散系数(ADC)值,记录肿块动态增强的时间-信号强度曲线(TIC)类型。结果钼靶X线摄影在50例检查者中42例发现病灶,单纯肿块27例,肿块伴钙化11例,单纯钙化4例;肿块多呈类圆形或卵圆形,28例肿块边缘清楚、光滑。MRI上11例为单一肿块,2例为非肿块型,病灶在T1WI上呈低或中等信号,在T2WI上2例肿块较小者呈高信号,11例呈等高混杂信号;11例肿块型中,边缘光滑4例,5例均匀强化,3例呈环形强化,3例不均匀强化;平均ADC值为1.2×10-3mm2/s,8例TIC呈Ⅲ型。结论 TNBC的钼靶X线及MRI表现有一定特征性,提高对特征性表现的认识有助于术前作出正确诊断。
[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，
