摘　　要：目的对磁共振扩散加权成像在胆管癌诊断中的临床应用价值进行研究,同时分析其效果。方法方便选取2018年3月—2019年3月该院接收治疗的胆管癌患者41例为胆管癌组,于同一时期选取41例肝占位病变患者为肝占位病变组和健康体检志愿者41名为对照组进行对比分析,3组均采用磁共振扩散加权成像进行诊断,并对诊断结果进行对比分析。结果胆管癌组的直径为(1.54±0.79)cm与肝占位病变组的(2.86±1.58)cm相比较,差异有统计学意义(t=4.785,P<0.05);胆管癌组的表观弥散系数(ADC)值为(1.35±0.12)mm2/100 s,分别与肝占位病变组的(2.15±0.42)mm2/100 s、对照组的(1.55±0.34)mm2/100 s相比较,差异有统计学意义(P<0.05);但是与恶性病变组比较,差异无统计学意义(P>0.05),与良性病变组比较,差异有统计学意义(P<0.05)。结论磁共振扩散加权成像在胆管癌诊断中,不仅能提供定量诊断信息,而且序列速度快,同时还具有图像特点清晰,ADC值准确等优势,是临床上肝胆内脏检查的一种有效手段,值得推广。Objective To study the clinical application value of magnetic resonance diffusion weighted imaging in the diagnosis of cholangiocarcinoma,and to analyze its effect.Methods 41 patients with cholangiocarcinoma who were treated in the hospital from March 2018 to March 2019 were conveniently selected as the cholangiocarcinoma group,and in the same period,41 patients with liver occupying lesions were selected as the liver occupying lesion group and 41 healthy physical examination volunteers were selected as the control group for comparative analysis.The three groups were diagnosed by MRI diffusion weighted imaging,and the diagnosis results were compared and analyzed.Results The diameter of the cholangiocarcinoma group was(1.54±0.79)cm compared with(2.86±1.58)cm of the liver space-occupying lesion group,and the difference was statistically significant(t=4.785,P<0.05);the appearance of the cholangiocarcinoma group(ADC value)was(1.35±0.12)mm2/100s,compared with(2.15±0.42)mm2/100 s in the liver-occupying lesion group and(1.55±0.34)mm2/100 s in the control group,and the difference was statistically significant(P<0.05);but compared with the malignant lesion group,the difference was not statistically significant(P>0.05),compared with the benign lesion group,the difference was statistically significant(P<0.05).Conclusion Magnetic resonance diffusion-weighted imaging in the diagnosis of cholangiocarcinoma can not only provide quantitative diagnostic information,but also has a fast sequence speed.At the same time,it has the advantages of clear image characteristics and accurate ADC value.It is an effective method for clinical examination of hepatobiliary viscera.It is worthwhile promotion.
