磁共振扩散加权成像在肝外胆管癌诊断中的应用研究

Application of weighted imaging in the diagnosis of extrahepatic cholangiocarcinoma diffusion magnetic resonance

目的分析磁共振扩散加权成像在肝外胆管癌诊断中的价值。方法对30例正常人群与30例肝外胆管癌患者的磁共振扩散加权成像的结果进行对比分析,以进一步探索磁共振扩散加权成像在肝外胆管癌诊断中的价值及临床意义。结果通过研究发现,在30例肝外胆管癌患者中,肝外胆管癌患者的表观扩散系数(ADC值)为(1.26±0.011)mm2/1000a;而正常人群组的ADC值为(1.50±0.019)mm2/1000 a,通过两独立样本t检验,结果表明两组之间ADC值差异具有统计学意义(P=0.017)。结论在对肝外胆管癌部位的影像学诊断中,磁共振扩散加权成像具有重要的临床应用价值。

【Objective】To analyze the diffusion weighted magnetic resonance imaging in the diagnosis of extrahepatic cholangiocarcinoma value. 【Methods】30 cases of normal people and30 patients with extrahepatic bile duct carcinoma with diffusion weighted magnetic resonanceimaging results were compared and analyzed, in order to further explore and clinical significance of magnetic resonance imaging diffusion weighted imaging in the diagnosis of extrahepatic cholangiocarcinoma value. 【Results】The study found that, in 30 cases of extrahepatic bile ductcarcinoma, apparent diffusion coefficient of patients with extrahepatic bile duct carcinoma table（ADC value） was（1.26 ± 0.011）mm2/1000a; and the normal group of apparent diffusion coefficient（ADC value） was（1.50±0.019）mm2/1000 a, by two independent samples t test, the results show that two groups of apparent diffusion coefficient（ADC value） the difference was statistically significant, P=0.017. 【Conclusion】 In the diagnosis of extrahepatic bile duct carcinoma parts of the image, and has important clinical application value of diffusion weighted magnetic resonance imaging.
