分析MRI多序列成像技术在诊断及鉴别乳腺癌中的应用价值

Analysis of the Application Value of MRI Multi-Sequence Imaging Technology in the Diagnosis and Differentiation of Breast Cancer

目的:探究MRI多序列成像技术应用于乳腺癌的诊断与鉴别诊断中的价值。方法:选择2017年7月~2019年7月本院收治的自愿进行MRI检查的乳腺癌患者44例进入观察组,选取同期自愿进行MRI检查的良性乳腺肿瘤患者44例进入对照组,比较两组比较T1WI、T2WI、DWI、DCE各序列下的MRI征象。结果:观察组MRI征象中的边缘强化、边缘不规则占比高于对照组;b值800s/mm2时,观察组ADC值低于对照组;DCE序列下,观察组时间-强度曲线中,流出型占比高于对照组,流入型占比低于对照组,差异有统计学意义(P<0.05)。结论:MRI多序列成像技术可比较理想地应用于乳腺癌的诊断与鉴别诊断中。

Objective:To explore the value of MRI multi-sequence imaging in the diagnosis and differential diagnosis of breast cancer.Methods:From July 2017 to July 2019,44 breast cancer patients admitted to our hospital for voluntary MRI examination were admitted to the observation group,and 44 benign breast cancer patients for voluntary MRI examination were selected to enter the control group,and the MRI signs of T1WI,T2WI,DWI and DCE sequences were compared between the two groups.Results:The proportion of edge enhancement and edge irregularity in MRI signs in the observation group was higher than that in the control group.When b value was 800s/mm2,ADC value in the observation group was lower than that in the control group.Under the DCE sequence,the proportion of outflow type was higher than that of the control group and the proportion of inflow type was lower than that of the control group in the time-intensity curve of the observation group,and the difference was statistically significant(P<0.05).Conclusion:MRI multi-sequence imaging technique can be applied in the diagnosis and differential diagnosis of breast cancer.
