摘要
目的探讨与对比多模态MR成像技术在不同病理分型乳腺癌中的诊断价值。方法采用回顾性、随机、抽样研究方法,选取2010年6月至2016年5月本院乳腺癌患者90例作为研究对象,所有患者均行多模态MR成像检查与病理分型分析,记录成像特征。结果 90例患者中,导管内癌10例,浸润性导管癌70例,浸润性小叶癌10例。乳腺癌不同分型患者的MRI形态与边缘情况对比差异无统计学意义(P>0.05)。导管内癌分型患者的MR时间-信号强度曲线(TIC)Ⅲ型+Ⅳ型比例都显著高于浸润性导管癌与浸润性小叶癌(P<0.05)。导管内癌分型患者的强化率、信号增强比率都高于浸润性导管癌与浸润性小叶癌,峰值时间显著下降,差异均具有统计学意义(P<0.05)。结论多模态MR成像技术可结合形态学及血流动力学信息,对不同病理分型乳腺癌的鉴别诊断具有一定价值,值得临床推广应用。
Objective To explore and evaluate the diagnostic values of multimodal MR imaging in different pathological types of breast cancer. Methods Using the retrospective randomized and sampling method, 90 cases of breast cancer diagnosed and treated in our hospital from June 2010 to May 2016 were selected. All patients underwent multimodal MR imaging and pathological typing analysis,and the imaging features were recorded. Results In the 90 patients,there were 10 cases of intraductal carcinoma,70 cases of invasive ductal carcinoma and 10 cases of invasive lobular carcinoma,which accounted for 11.1%,77.8% and 11.1%,respectively. There were no significant differences in the contrast amongst the MR morphology and the marginal condition of the patients with different types of breast cancer(P>0.05). The proportion of MR TIC type Ⅲ and type Ⅳ in patients with intraductal carcinoma were significantly higher than that of invasive ductal carcinoma and invasive lobular carcinoma(P<0.05). The enhancement rate and signal enhancement ratio of intraductal carcinoma patients were all higher than those of invasive ductal carcinoma and invasive lobular carcinoma. The peak times were decreased significantly,and the difference compared among the patients were statistically significant(P<0.05). Conclusion The multimodality MR imaging can combine morphological and hemodynamic information to improve the differential diagnostic value of breast cancer with different pathological types,so it is worthy of popularization and application.
