摘　　要：目的探讨磁共振成像(magnetic resonance imaging,MRI)弥散加权成像(diffusion weighted imaging,DWI)对肝门部胆管癌侵袭性的预测评估价值。方法选取2017年2月至2019年1月在本院治疗的61例肝门部胆管癌患者作为研究对象,所有患者均需接受MRI检查,分析检查结果。结果TNM中,Ⅳ期患者表观弥散系数(ADC)值高于Ⅱ期、Ⅲ期、Ⅳ期患者,差异有统计学意义(P<0.05);Ki-67指数>10%患者的ADC值低于≤10%患者,比较差异有统计学意义(P<0.05)。结论MRI检查中DWI为评估肝门部胆管癌侵袭性的有效影像学检查手段,可为临床诊治提供有效参考。Objective To investigate the predictive value of diffusion weighted imaging(DWI)of magnetic resonance imaging(MRI)in the evaluation of invasiveness of hilar cholangiocarcinoma.Methods 61 patients with hilar cholangiocarcinoma treated in our hospital from February 2017 to January 2019 were selected as the research subjects.All patients received MRI examination,and the results were analyzed.Results In the TNM,the apparent diffusion coefficient(ADC)of stage Ⅳ patients was higher than that of stageⅡ,Ⅲ and Ⅳ patients,the difference was statistically significant(P<0.05).The ADC value of patients with Ki-67 index>10%was lower than that of patients with Ki-67 index≤10%,the difference was statistically significant(P<0.05).Conclusion In the MRI examination,DWI is an effective imaging method for evaluating the invasiveness of hilar cholangiocarcinoma,which can provide effective reference for clinical diagnosis and treatment.
